2. There are 2 types of underfloor
heating systems:
• Electric underfloor heating – dry system
• Hot water underfloor heating – wet system

3. Running costs Vs installation
• Electric is the cheapest and
easiest system to install, but
very costly to run.
• Wet systems can be
powered by a range of
different boilers giving a
wide range of possible
running costs.
Installation
Cost per
annum
Electric £900 £215
Gas boiler £1350 £65
Heat pump £1350 £23

4. Powering your
underfloor heating
What will make the biggest savings
to your back pocket is going to be
what fuel source you use to power
your underfloor heating system.

5. When you have a renewable energy
product such as a biomass boiler, air
source or ground source heat pumps
installed you will earn money from the
Renewable Heat Incentive! (RHI)
If you have access to a good source of
free firewood, it could even be worth
having a simple log burner installed
with a back boiler to power your
underfloor heating system.

6. What flooring to use?
Using the wrong types of flooring could
damage your home…

8. Simple guidelines:
Concrete floor – no need to
insulate under the pipes as the
concrete will hold the warmth like
a thermal store and keep the rooms
warm once the heating has been
turned off.
Wood floors – you WILL need to
have insulation installed beneath
the pipes to prevent the heat being
wasted

9. Simple guidelines:
Ceramic tiles– without any doubt
ceramic tiles are the best flooring you
can use to really feel the most from
your underfloor heating as they are
fantastic heat conductors.
Wood flooring – wood is an insulator
and can work with low temperature
underfloor heating.
Carpet – carpet also being an insulator
is fine as long as the Tog rating of the
carpet is below 1.5 otherwise you will
not feel much benefit.

10. Best Underfloor
Heating Solution
To get the maximum amount of
warmth as well as financial
benefit we recommend having a
Nibe air source heat pump fitted
to power your underfloor
heating system and have the
total cost covered by the RHI
scheme.
Having ceramic tiles in kitchen,
living room and bathrooms will
also give added value.
