Stop burning cash. Start tapping into the earth.
A lot of people hear about ground source heat pumps and think:
“How can 10°C from the ground possibly heat my house?”
Fair question. The truth is it doesn’t. Not directly.
So what’s actually going on?
The ground gives you a steady source of low‑grade heat usually somewhere between 8 and 13°C, depending on the depth, the soil and the local conditions.
That temperature on its own is useless for heating a house.
What matters is what happens next.
The heat pump takes that low-level energy and lifts it.
It pulls heat out of the ground, passes it through a refrigerant, and then compresses it which raises the temperature to something you can actually use for heating and hot water.
So you’re not heating your home from 10°C.
You’re taking stable background energy and upgrading it into proper, usable heat.
One important thing people often miss: the lower the temperature your system needs to run at, the better the whole thing works.
What does it feel like to live with it?
It’s very different from a boiler.
No bursts of heat. No cycling on and off. No hot then cold.
Just a steady, even temperature across the whole house.
It works particularly well with radiant systems like wall heating or ceiling panels where heat is delivered gently through surfaces rather than pushed around with air.
The result is simple: the house just feel right!
Not stuffy, not dry, not uneven. Just comfortable.
And in summer?
It flips. Instead of bringing heat in, it takes excess heat out of the house and sends it back into the ground.
That gives you a softer kind of cooling, not air-con blasting cold air at you, just keeping the house from overheating.
At the same time, you’re doing something useful in the background:
you’re putting some of that heat back into the ground after winter.
So over time, the system stays balanced instead of being constantly drained.
At PATH‑50, that’s exactly what we focus on, not just installing systems, but getting the whole building right so it actually delivers comfort in real life, not just on paper.
