These boilers are also energy-efficient (endorsed by the Energy Saving Trust) and offer a standard warranty.

Potterton Heat-Only Boiler Prices
Heat-only (or regular) boilers require a cold water tank and hot water cylinder. The advantage is that you’re able to use hot water in several locations simultaneously.
However, having these separate components means that you will need to factor in the price of a hot water cylinder and a cold water tank. Nonetheless, it is still a cost-effective solution for your heating.
Potterton’s regular boilers range from 12kW models (one-bedroom flat) to 30kW (three-bedroom homes with up to two bathrooms).
| Boiler Name | Power Output | Warranty | Example of Suppliers | Pricing |
