Underfloor heating. Air source heat pumps. Two of the most energy-efficient heating solutions available for modern homes in Scotland.
But the big question is:
Can they work together?
(Spoiler alert: They’re a match made in low-carbon heaven.)
In this guide, we’ll explain how underfloor heating and air source heat pumps complement each other, when it makes sense to pair them, and what you need to consider before installing both.
🔥 Why Heat Pumps and Underfloor Heating Are a Perfect Pair
Air source heat pumps (ASHPs) work by extracting heat from the air outside and transferring it indoors. They operate at lower flow temperatures than gas boilers — usually between 35°C and 55°C.
That’s exactly why underfloor heating is ideal:
- 🟢 It works efficiently at low temperatures
- 🟢 It covers a large surface area, spreading heat evenly
- 🟢 It helps reduce energy use while keeping your home comfortably warm
In other words: heat pumps love underfloor heating. And so will you!
🏠 When Is It Best to Use Underfloor Heating with a Heat Pump?
Underfloor heating makes the most sense when:
- You’re renovating or building an extension
- You’re in a new-build or whole-home retrofit
- You want to upgrade from radiators to a sleek, invisible heating solution
- You’re installing air-to-water heat pumps (which heat water for space heating and hot water)
Many homeowners in Edinburgh and the Lothians opt for a hybrid solotion:
- Underfloor heating in kitchens, living areas, or bathrooms
- Radiators in upstairs bedrooms and smaller rooms
It’s the best of both worlds — and we can help you design a system that works beautifully.
🛠 What Type of Underfloor Heating Works with Heat Pumps?
There are two main types:
1. Wet (Hydronic) Underfloor Heating
✅ Ideal for use with air-to-water heat pumps
✅ Warm water circulates through pipes under your floor
✅ Suitable for most floor types (timber, tile, laminate, etc.)
This is the most compatible and energy-efficient option for heat pumps. It’s what we recommend and install most often.
2. Electric Underfloor Heating
⚠️ Not ideal for use with a heat pump
❌ Works independently with electricy, often at higher costs
❌ Less efficient for whole-home heating
Electric systems are best for small, isolated areas (like a single bathroom)
🧰 Can Underfloor Heating Be Retrofitted?
Yes — but it depends on your property.
We’ll assess:
- Floor construction (solid concrete vs suspended timber)
- Floor-to-ceiling height
- Whether it’s possible to lift or level floors
📏 What If Only Some Rooms Have Underfloor Heating?
No problem. With a properly zoned system, your heat pump can for example:
- Heat radiators in bedrooms and hallways
- Run underfloor heating in your kitchen or living room
- Balance flow temperatures to ensure everything stays toasty
We’ll design a setup that works with your lifestyle, layout, and budget.
💷 Will This Increase the Cost?
Adding underfloor heating does increase upfront costs, but offers:
- Lower running costs over time
- Even, consistent warmth
- Energy savings — especially when paired with a well-insulated home
