What happens when a heat pump gets old? 👀
The original ground source heat pump at this property had been doing its job for an impressive 17 years and was still meeting the home's heating needs.
But with manufacturer support for the older IVT unit no longer available, the homeowner decided the time was right to replace it.
In its place, we've installed a new 13kW NIBE S1156 ground source heat pump, while keeping the parts of the existing system that were still perfectly good, including the slinky ground array, radiators, cylinder and buffer.
The new heat pump even sits in the same spot in the garage plant room, making this a relatively straightforward upgrade to an established ground source heating system 👍
