Very simple visual description of how a ground source heat pump works. Ground source heat pumps are a renewable source of heating that extract heat from the ground to heat your home and hot water. They are eligible for the government's Renewable Heat Incentive subsidy.

1. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)

2. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)
Liquid,
heated in
tubes
underground,
travels into
the GSHP

3. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)
The liquid
gives up
this heat
from the
ground at
the heat
exchanger

4. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)
The
refrigerant
liquid takes
that heat
and turns
into a gas

5. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)
The warm
gas is
compressed
by the
compressor.
This makes
it hot.

6. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)
The hot gas
gives up
this heat at
the heat
exchanger

7. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)
The water from
your central
heating system
takes up this
heat and heats
your house.

8. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)
The water from
your central
heating
system takes
up this heat
and heats your
house.
Hooray!

9. INSIDE A GSHP
(GROUND SOURCE HEAT PUMP)
The now liquid
refrigerant is
cooled through
the expansion
valve ready to
start again

This process
repeats until
your house
is warm and
toasty
