Ground Source Heat Pump
- Product information
- Advantages
The NIBE F1355 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. The F1355 features inverter-driven compressors, meaning the heat pump can gradually increase or decrease heat production, depending on the demand. 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 F1355 comes in two 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 F1355 is easy and reassuring. It’s eligible for the £7,500 Boiler Upgrade Scheme grant, helping reduce upfront costs. Choose a NIBE Pro installer and you’ll get an extended warranty for extra peace of mind. Additionally, the F1355 is eligible for FlexiServ; servicing carried out by NIBE’s own engineers to keep everything running smoothly. Day to day, the myUplink app lets you check in and adjust settings from your phone or tablet, giving you simple, convenient control wherever you are.
