Frequently Asked Question
Can underfloor heating be installed in existing homes?
Yes! At Heat Flow, we specialise in retrofit underfloor heating solutions in Birmingham. We offer low-profile and overfloor systems that don’t require digging up your floors — making them perfect for renovations, extensions, and older properties.
What’s the difference between water and electric underfloor heating?
Water underfloor heating systems use warm water through pipes, making them ideal for larger areas and energy efficiency. Electric UFH uses cables or mats and is better suited for smaller spaces like bathrooms. We install both based on your property needs and budget.
How much does underfloor heating cost to install?
Costs depend on the system type, area size, and floor type. For example, screed underfloor heating for new builds is more cost-effective per m² than retrofitting into existing floors. We offer free online quotes — just send us your room sizes or plans.
Is underfloor heating more efficient than radiators?
Yes. Underfloor heating runs at lower temperatures but spreads heat evenly, reducing energy usage by up to 30%. Our Birmingham clients often see lower energy bills and greater comfort compared to traditional radiators.
What flooring types are compatible with underfloor heating?
Most floor finishes work well with UFH, including tile, engineered wood, laminate, and vinyl. We’ll advise the best screed and installation method based on your flooring choice to ensure maximum heat output and system longevity.
Can I get a quote without a home visit?
Absolutely. Our online quote system allows you to upload photos, room sizes, or plans. We’ll provide a detailed quote for your underfloor heating or plumbing work in Birmingham without needing an initial site visit.
What is screed underfloor heating and when is it used?
Screed underfloor heating involves embedding UFH pipes into a liquid screed layer. It provides excellent heat transfer and is ideal for new builds or full renovations. We use high-quality screeds for smooth finishes and efficient heating.
Do you also install boilers and heat pumps?
Yes, we offer full plumbing and heating integration, including boiler upgrades and heat pump installation. Whether you need a new heat source or want to connect to an existing system, our team will handle everything safely and professionally.
Water Underfloor Heating FAQ's
What is water underfloor heating and how does it work?
Water underfloor heating (also called wet UFH) uses warm water circulated through pipes beneath the floor surface. The heat rises evenly across the room, delivering energy-efficient comfort and working well with boilers or heat pumps.
Can I install water underfloor heating in an existing home?
Yes. At Heat Flow, we offer retrofit-friendly options like joisted floor systems and low-profile panels that are ideal for older homes or renovations without needing to dig up the floors.
Is water underfloor heating more efficient than radiators?
Absolutely. Water-based UFH runs at lower temperatures than radiators (around 35–45°C vs 70–80°C), reducing energy use while providing steady, even warmth throughout your home.
Which floors are suitable for water underfloor heating?
Water UFH works well under tiles, engineered wood, laminate, vinyl, and even carpet. We tailor the system design to suit your flooring type for maximum heat output and comfort.
How long does installation take?
Installation time depends on the project size. A single room might take 1–2 days, while full home systems with screed-based underfloor heating may take up to a week including drying time.
Is water underfloor heating safe and reliable?
Yes. Our systems use pressure-tested, oxygen-barrier pipes and high-grade materials designed to last for decades. Once installed, it’s extremely low-maintenance and safe under all flooring types.
Can I control different rooms separately?
Yes. We offer zoned heating systems with smart thermostats, allowing you to control each room’s temperature individually for improved energy efficiency and comfort.
Do I need a special boiler or heat source?
Water underfloor heating works with most modern boilers and is especially efficient when paired with air source or ground source heat pumps. We’ll recommend the best option for your home during your free quote.
Screed Underfloor Heating FAQ's
How long does screed underfloor heating take to install?
Installation can take 2–5 days, depending on project size and screed drying time.
Can I use it with any flooring?
Yes! Tile, wood, vinyl, and laminate all work well over screed UFH.
Is it energy efficient?
Absolutely. Screed UFH retains heat longer, needing less energy to maintain warmth.
Is screed UFH compatible with heat pumps?
Yes. It’s one of the best options for low-temperature systems like heat pumps.
Can I control each room separately?
Yes. We offer zoned controls and smart thermostats for individual room temperature.
Is this good for large open areas?
Yes, it’s ideal for large floor areas with continuous flow heating.
Do you offer online quotes?
Yes! Upload your floor plan or measurements for a fast, no-obligation quote.
How thick is the screed layer?
Usually between 50–65mm depending on insulation and flooring type.
Rapid Response UFH FAQ's
How fast does rapid underfloor heating warm up?
Most systems heat the floor surface in 20–30 minutes, depending on the floor covering and insulation.
Is it suitable for old homes?
Yes. It’s ideal for retrofit projects because it doesn’t require deep screeds or high floor buildup.
What’s the difference between this and standard UFH?
Rapid response systems are lighter, thinner, and have quicker thermal response times than screed-based systems.
Can I use it under wood or vinyl?
Yes. We adjust the temperature and recommend specific panel types for each flooring material.
Is it more expensive than traditional UFH?
Initial material costs can be slightly higher, but installation is quicker and energy savings are significant.
Will it work with my current boiler?
Yes. It works with all standard boilers and heat pumps, just like standard water-based UFH.
Can I control the temperature easily?
Yes. All systems support zoned smart thermostats with programmable timers.
Where Rapid UFH Works Best
✅ Kitchen and bathroom renovations
✅ Garden rooms and lofts
✅ Existing floor upgrades
✅ Homes with time-sensitive heating needs
Joisted Underfloor Heating FAQ's
Can you install UFH on suspended wooden floors?
Yes! Joisted UFH is specifically designed for timber floors using spreader plates or boards between joists.
Does it require floor buildup or screed?
No. It’s a dry-fit system that doesn’t involve concrete or floor height increases.
Is joisted UFH efficient?
Yes, when combined with proper insulation and smart controls, it delivers excellent energy savings.
Is it suitable for older homes?
Absolutely. It’s the best UFH option for period or character properties with timber structures.
Can I control rooms separately?
Yes. We install smart zoned controls and thermostats for individual rooms.
How long does installation take?
Most projects take 1–2 days depending on floor size and access.
Can you quote without visiting?
Yes! Submit your floor plans or room sizes and we’ll prepare a remote quote.
Will it work upstairs?
Yes, joisted UFH is great for upper levels because it’s lightweight and doesn’t affect ceiling heights.
Plumbing & Heat Sources FAQ's
Do I need a new boiler for underfloor heating?
Not always. We’ll assess your current system. Many modern boilers are compatible with UFH, but heat pumps may offer better efficiency.
Can I use a heat pump with radiators and UFH?
Yes! Hybrid and multi-zone systems allow both to work in one home.
Are you Gas Safe registered?
Yes, all our engineers are fully qualified and registered for gas installations.
What’s the best heat source for energy savings?
Air source and ground source heat pumps offer the best long-term savings, especially when combined with UFH.
Will you install plumbing for my bathroom too?
Yes, if we’re already working on your home’s heating or plumbing system, we can add bathroom pipework as part of the project.
Do you provide hot water system upgrades?
Absolutely. We can install cylinders, pumps, thermostatic mixing valves, and smart controls.
Do you offer both supply and install?
Yes. We handle product supply, design, installation, and aftercare – all in one place.
