Frankfurt ISH 2027: HVAC + Water building services

Frankfurt ISH, officially positioned as the international trade fair for HVAC + Water, takes place from 15 to 19 March 2027 at Messe Frankfurt in Frankfurt am Main, Germany. Its nine solution fields cover bathrooms, pools and spas, water-bearing systems, installation, heat generation, indoor air, intelligent building management, software, and sanitary and HVAC production. The organiser identifies skilled trades, engineering, distribution, architecture, construction, property, utilities and public facilities among its visitor groups. The 2027 programme lists talks, guided tours, awards, special areas, a festival and startup features. Admission is trade-only from Monday to Thursday; public visitors are also admitted on Friday.

A prepared visit can help you compare relevant products, clarify technical questions and identify suppliers for follow-up. In 2025 the organiser reported 2,182 exhibitors and more than 163,000 trade visitors from 149 countries. These figures describe the previous edition, not the 2027 forecast. Use the current exhibitor search and programme to plan around the companies and activities relevant to your work.

Why Frankfurt ISH matters

The organiser’s “Power of Solutions” theme focuses on how building technologies work together in response to sustainability, energy efficiency, comfort and customisation. The nine solution fields make the event relevant across several building-services disciplines. For professionals working on connected systems, this breadth can support comparison and help reveal questions that cross product categories. It does not confirm that products are compatible; verify interfaces and performance for the intended application.

The previous edition’s reported scale provides context for the international comparison environment: 2,182 exhibitors and over 163,000 trade visitors from 149 countries in 2025. It does not establish how many exhibitors or buyers will attend in a particular product segment in 2027. Check current listings before deciding which suppliers to visit.

Who should visit Frankfurt ISH?

Installers, plumbing specialists and skilled trades

Compare fittings, water-bearing systems and installation solutions, alongside related heating and indoor-air products. Focus on installation sequence, connections, accessories, service access and product documentation. Bring project conditions that affect fit, and request evidence for any claim that would influence your recommendation.

Building-services engineers and technical planners

Review heat generation, ventilation, water systems, controls and software against project requirements. Ask about operating limits, interfaces, technical data and system dependencies. Treat cross-system compatibility as a point to verify in documentation, not an assumption based on an exhibitor conversation.

Wholesalers, retailers and distributors

Use the product fields to identify suppliers and assess whether a range could fit your portfolio and customer groups. Compare product coverage, technical support and route-to-market questions. A directory listing or first conversation is not a confirmed distribution arrangement; record terms and next steps for later verification.

Architects, designers, project planners and real-estate professionals

Explore bathroom, pool and spa, indoor-air and building-management solutions in relation to project use, design and building performance. Compare appearance alongside dimensions, installation conditions, maintenance and coordination with other systems. Use the fair to shortlist options for closer review, then confirm specifications with suppliers.

Building operators, utilities and public-facility decision-makers

Focus on operational requirements, system renewal, service needs and the fit of building technologies with existing facilities. The organiser names industrial and commercial building operators, utilities, local authorities, municipal facilities, education and healthcare among visitor-company groups. Use supplier discussions to define evidence needed for a later technical or procurement assessment.

What can you find at Frankfurt ISH?

The organiser uses nine solution fields to help visitors navigate the fair. The current exhibitor and product search should be used to identify specific companies and offerings.

Bathrooms

Compare sanitary and bathroom products for design, dimensions, materials, installation and maintenance. Installers can focus on fit and service questions; designers can note finishes and project constraints. Confirm exact ranges and technical details with suppliers.

Pools & Spas

The 2027 programme identifies a Pools & Spas special area presenting integrated solutions for comfortable, hygienic and resource-efficient wellness experiences. Use the area to frame questions about components and operations; confirm current exhibitors and product details in the organiser’s information.

Water-bearing systems

Review water-system products, pipework and connections with application conditions in mind. Ask for intended-use information and system documentation; do not assume that products are compatible simply because they appear within the same field.

Installation

Examine how building-services components are assembled and coordinated. Compare installation steps, access, connections and service implications, and request system information where components are intended to work together.

Heat generation

Explore heating-related technologies against the needs of a defined building or project. Ask which performance data, operating conditions, installation requirements and service arrangements apply to the specific product. Verify savings or performance statements for the relevant application.

Indoor air

Review ventilation and related technologies in the context of building use, comfort and system coordination. Ask for application-specific performance data, controls information, installation details and maintenance requirements.

Intelligent building management

Consider monitoring and control solutions in relation to the systems a building already uses. Ask about interfaces, supported systems, data requirements and integration. Confirm compatibility and security needs against your own technical requirements.

Software

Define the planning, management or operating workflow you want software to support. Ask about functionality, system dependencies, data exchange and technical support, and verify the fit with your existing environment.

Sanitary & HVAC production

Manufacturers and production professionals can explore solutions associated with sanitary and HVAC production; buyers can identify suppliers for further discussion. Confirm the product scope, specifications, service requirements and test conditions with the provider.

What makes Frankfurt ISH different?

The “Power of Solutions” concept connects the fair’s broad product range with the organiser’s focus on technologies working together. Nine solution fields span water and sanitary applications, installation, heating, indoor air, building management and software. This can help visitors identify adjacent questions as well as products in their main area of interest.

The 2027 programme page lists conferences and talks, awards, special areas, the ISH Festival, startups, and guided tours and talks. It names Green Roofs & Facades, described as showing how roofs and facades can retain water, reduce heat and generate energy, and a Pools & Spas special area. Check the current organiser schedule for confirmed session titles, participants and times; programme formats do not guarantee a particular session.

In 2025, the organiser reported 2,182 exhibitors and more than 163,000 trade visitors from 149 countries. The previous edition’s figures indicate international scale but are not a 2027 exhibitor list, segment forecast or guarantee of access to a buyer.

What should you aim to achieve?

For installers and service professionals

Compare a short list of products against the same installation, connection, service and documentation criteria. Leave with exact product names, unresolved questions and the technical material needed before recommending an option.

For engineers and planners

Choose a system-integration or performance question. Record the data needed for design review, separate documented specifications from statements to verify, and note which supplier contact can provide each item.

For distributors

Identify suppliers or product groups that could address a defined portfolio need. Compare range, support information and commercial questions for later discussion; do not treat an introductory conversation as an agreement.

For building owners and operators

Use a real operational or project requirement to shortlist technologies for assessment. Note the evidence, service information and compatibility checks required before procurement or specification.

How to prepare before Frankfurt ISH

1. Set a clear objective

Write down the decision or question you want the visit to support: for example, comparing a defined heating application, reviewing installation options, finding software for a workflow or shortlisting sanitary products. A specific objective helps you decide which solution fields deserve time.

2. Search for relevant exhibitors and products

Use the organiser’s exhibitor and product search to build a shortlist. Save the company, product field and reason for visiting in your own notes. A directory entry is a research lead; confirm current participation and product details through the latest organiser information.

3. Prioritise meetings

Mark essential conversations as A, useful comparisons as B and exploratory stops as C. The organiser says visitors can connect with exhibitors in advance using its networking tool. Arrange relevant meetings where possible, while keeping time for product discovery and follow-up questions.

4. Prepare technical questions

For sanitary products, consider dimensions, finishes, installation and maintenance. For water systems, ask about connections, applications and components. For heating and indoor air, identify operating conditions and performance evidence. For controls and software, ask about interfaces, dependencies and support. Request documentation for claims that affect a project or purchase.

5. Review the programme and admission conditions

The organiser lists talks, guided tours, awards, special areas, a festival and startups. Check the current schedule before planning around any session. Confirm ticket conditions and admission rules as well: the first four days are trade-only, while public visitors are also admitted on Friday.

6. Prepare a comparison record

For each supplier, record the company and product, the need it may address, evidence requested, contact, open question and next action. Keep confirmed specifications separate from personal impressions and claims that need verification. This makes post-fair comparison more reliable.

How to make the most of the exhibition

Do not try to see every stand. Use the official solution fields to organise your route around priorities, confirmed meetings and published programme items. Compare alternatives against the same requirements while the details are fresh. If a conversation changes your needs, adjust the shortlist rather than following a fixed route for its own sake.

At each stand, explain your role and the product or project question you are evaluating. Ask for the information relevant to that decision. Record exact product names and variants, technical documents requested, the contact and the next step. Mark uncertain statements as open questions, not confirmed specifications.

For projects crossing disciplines, consider whether you need to compare more than one solution field. An engineer may need to check how controls relate to heating or ventilation; an installer may need to connect a water product with its installation requirements. Ask suppliers to verify interfaces directly.

Review your notes at the end of each day. Remove duplicate leads, identify unanswered questions and choose which suppliers merit a return visit. This makes the next day more focused and preserves time for useful conversations.

Plan your time at Frankfurt ISH

The fair runs for five days. The organiser publishes opening hours of 09:00–18:00 from Monday 15 to Thursday 18 March 2027, and 09:00–17:00 on Friday 19 March. Trade visitors have exclusive admission during the first four days; public visitors are also admitted on Friday. Check current visitor information for any later changes.

Before the day starts

Review priority companies, confirmed meetings and sessions. Use the organiser’s current floor plan and exhibitor directory to plan locations; do not infer hall placement from a product category. Keep a flexible block for discoveries or follow-up conversations.

Morning and midday

Use early hours for essential meetings and comparisons. Record the same criteria for each comparable product. At a break, review notes and decide whether the afternoon should address a gap, a second supplier or a programme item.

Afternoon and close

Visit secondary targets or a confirmed special area or talk. Leave time to return to a stand with a technical question. At day’s end, record what is confirmed, what remains open and who owns each follow-up action.

Beyond the exhibition floor

The 2027 programme page lists conferences and talks, awards, special areas, the ISH Festival, startups, and guided tours and talks. It also names Green Roofs & Facades and Pools & Spas. These formats can add context to product research, but exact sessions and times should be taken from the current organiser schedule.

Choose programme items because they answer a question relevant to your work. After a talk or tour, record the practical point, any source or evidence to follow up, and how it relates to a product or project decision. The organiser’s online library includes selected 2025 presentations; these are previous-edition material, not confirmation of 2027 sessions.

Networking and supplier conversations

The organiser’s visitor information says attendees can connect with exhibitors before ISH and use a networking tool to arrange meetings. Prepare a brief introduction: your role, the product field and what you need to evaluate. For technical discussions, state the application and question; for distribution, explain the portfolio need; for building operators, describe the operational requirement without sharing sensitive details unnecessarily.

Close each discussion by confirming the next step, the document or information expected, who will provide it and how to follow up. For claims that affect a design or purchase, request written evidence or a technical contact. A meeting tool supports preparation but does not guarantee a meeting, buyer access or a commercial result.

Visitor access, tickets and opening times

The organiser’s visitor pages provide ticket and admission information, opening times, travel and accommodation guidance, an exhibition-grounds plan, exhibitor and product search, programme information and a networking tool. The pages reviewed identify Messe Frankfurt in Frankfurt am Main but do not confirm every 2027 transport, shuttle or parking arrangement. Check current arrival information before travelling.

The organiser states that tickets can be purchased through its ticket shop or on site; on-site ticket-counter payments are cashless. Check the current ticket page for prices and conditions. Do not assume prior-edition prices or policies remain valid.

Hours are 09:00–18:00 Monday to Thursday and 09:00–17:00 Friday. Trade-only admission applies from 15 to 18 March; public visitors may also attend on 19 March. Confirm the schedule before arranging meetings or travel, particularly for Friday.

One day or several days?

A one-day visit can work when your objective is narrow and your supplier shortlist is ready. With nine solution fields and a multi-day programme, visitors with wider responsibilities may need more time.

One day

Prioritise essential suppliers and one or two relevant programme items. Use the directory before arrival, keep comparisons focused and leave time for notes. If your project spans several fields, select the most important links rather than trying to cover everything.

Two days

Two days may suit visitors comparing suppliers across related fields. Use one day for the main product area and the next for adjacent systems, a confirmed programme item or follow-up conversations. Review notes between days so the second visit closes gaps.

Three or more days

A longer visit may help when you manage several product categories, a complex project or multiple meetings. Spread priorities across the days, reserve time for confirmed programme items and keep room to revisit suppliers. The schedule should follow your objectives, not the assumption that every hall must be covered.

Frankfurt ISH for active projects

Bring a concise project brief: application, project stage, functional need, systems involved and open questions. Keep confidential information private unless you have decided it is appropriate to share. For heating or indoor-air work, note operating context and required performance evidence. For sanitary, water or installation products, capture dimensions, connections, materials, maintenance access and site constraints. For controls and software, list the systems and workflows to be supported.

Use supplier discussions to gather comparable information, not to approve a design on the spot. Request specifications, installation documents, service information and evidence for performance claims. Identify which colleague will review each item. The visit can produce a shortlist; site-specific design, compliance checks and procurement assessment remain separate steps.

After Frankfurt ISH

Within a few days, sort contacts into immediate project or purchasing relevance, potential future fit and general market information. Link each contact to a product, question and next action. For priority suppliers, request the promised specifications, installation details, compatibility information or service documentation.

Compare the information against your project requirements and alternatives. Check which product variant the evidence covers and ask for written support for claims that matter. For future contacts, record the condition that would make a follow-up useful. Remove duplicates and correct names while the event is still fresh in mind.

Share the shortlist, comparison criteria, open questions and follow-up owners with colleagues. Agree what evidence remains missing and who will verify it. This helps distinguish a promising conversation from an evaluated product or supplier.

Who should consider exhibiting?

The official solution fields include bathroom, pool and spa, water-bearing, installation, heat-generation, indoor-air, building-management, software, and sanitary and HVAC production solutions. Companies whose products fit those areas may consider exhibiting when they have a defined reason to present to building-services professionals, distributors, planners or operators.

Set an objective such as product feedback, relevant technical discussions, distributor research or visibility among a defined professional group. Decide how the team will record conversations and follow up. The 2025 visitor and exhibitor figures describe the previous edition; they do not guarantee 2027 attendance, target-buyer access, leads or sales. Review current exhibitor information for costs, deadlines, stand options and services, which are not confirmed in the visitor information reviewed here.

Heating, cooling and ventilation opportunities in Germany

Market size and demand

The evidence reviewed for this update did not establish a current Germany-specific market-size or demand figure for HVAC and water-building services. The event’s previous-edition attendance is not a measure of German product demand. Commercial decisions should use current product-level market evidence and project requirements.

Regulations and potential areas to investigate

The European Commission states that Ecodesign requirements under Regulation 2027/2281 apply to specified air-heating products, cooling products, high-temperature process chillers and fan coil units. Requirements include product information, energy efficiency and nitrogen-oxide emissions, and are mandatory for manufacturers and suppliers wishing to sell covered products in the EU. Product scope and obligations vary by category and technical limits; confirm the rules for each product.

• For exhibitors: manufacturers and importers of covered products may use technical discussions to clarify product scope and the compliance documents buyers may request. This regulation does not demonstrate German market demand or guarantee sales.
• For visitors: engineers, buyers and operators may ask suppliers for product-specific efficiency, emissions and technical information relevant to procurement or design. Verify applicability and evidence for the model and use case.
