The NIBE F1345 is a powerful ground source heat pump. It delivers steady, reliable warmth, making it an ideal choice for larger homes, country estates, historic buildings, and big family houses. Thanks to an A+++ energy rating and the steady temperature of the ground, it runs efficiently and keeps indoor temperatures consistent through changing seasons.
The F1345 comes in four output options so your installer can choose the best match for your property, and, if you need even more capacity, it can be paired with up to nine other NIBE heat pumps to heat very large buildings without compromise. It fits seamlessly with your wider home setup, integrating with NIBE ventilation systems, solar inverters, pools, or an additional heat sources for a complete, future-ready solution.
Living with the F1345 is easy and reassuring. It’s eligible for the £7,500 Boiler Upgrade Scheme* grant, helping reduce upfront costs.
