Heat Pumps
An introduction
What is a Heat pump?
A heat pump is a machine
which is used to heat your
house in place of a
conventional fossil fuel boiler.
Renewable Heat?
Heat pumps use electricity to run.
For each kWhr or unit of electricity used the heat pump
grabs hold of 2 or 3 units of heat from the air or
ground.
The heat from the air / ground is renewable, it is
replenished by the sun.
So this part is renewable.
As a result Heat pumps are a 50 -75% renewable heat
source.
How does it fit in my house?

• The EHS range of heat pumps
will heat water up to 55C.
• Available in sizes from 9 and
16kW suitable for houses of up
to 300 m^2
• Suitable for heating and hot
water provision serving ufloor
heating and or radiators.
Is it noisy?
• The noise level is 56 dBa
• My car is 61 dBa on tick over
Is it a simple swap for my boiler?
Radiators
• Radiators don’t work the same on heat pumps as they
do on boilers.
• The temperature is lower.
• The heat output is lower so bigger radiators need to be
installed
Under floor heating
Under floor heating
runs at 45C so is
perfect for heat pumps.

Why Choose a Heat Pump?
New build
In new build developments 20% of energy use must come from a
renewable source. Installing heat pumps in some of the houses
helps to meet this target.
In 2016 Code 5 is introduced, from this point on gas boilers will
no longer be an option in new builds.

Run Costs 120m^2 house
July 2011 Ofgem figures
Average electricity usage of 3,300 kWh @ 13p/kWhr or
£429 per year for lighting, domestic appliances etc.
Average gas usage of 20,500 kWh @ 4.9p/kWhr or
£1006 for heating and hot water
at 84% efficient this provides 17136 kWhrs of heat
Run Costs 120m^2 house

Is a heat pump suitable for my
House?
Insulation level
Heat pumps suit well insulated properties best.
They do not suit very large or badly insulated properties.
Example:
in a Code 3 house a heat pump will cost £30 / m^2
In a 1980s house this will cost £50 / m^2
In a 30s cavity walled house they will cost £70 / m^2
And in a solid walled house they can cost £100 / m^2
EST* Advise to End Users
When you should consider a heat
pump
We particularly recommend considering a
heat pump if your home is one of the
approximately five million properties that
are off-gas, or for a new-build property.
Heat pumps are not recommended to
replace gas boilers at this time.
*Energy saving trust
Payback Times
Assuming a 120m² house:
HP installation will cost £7000, gas boiler would be £3000.
Oil boiler installation would be £6000.
The Heat Pump will cost £651 p/a the gas boiler £1005 p/a
The oil boiler will cost £1142. p/a
Payback:
vs. gas saving is £350/ yr. Installed cost is £4000 more,
payback is 11.5 years
vs. oil saving is £491/ yr. Installed cost is £1000 more,
payback is 2 years

Off grid and fuel security
5 M households in England, do not have
access to the gas network,
The number of claims made for stolen
fuel spiralled by 264 per cent in January
2011.
Incentives
Are there any incentives available to help?
RHPP
From August 2011 a one off payment of £850 is available if
you have a heat pump installed. This scheme ends in March
2012.
VAT
In retro-fit heat pumps have only 5% vat
In new build heat pumps have 0% vat
RHI
In October 2012 there will be an run cost rebate from the
government called the renewable heat incentive.
