Renewable Energy Guides, Advice & Insights

Insights into renewable energy and low-carbon heating, including heat pumps, energy efficiency, sustainability, and reducing household energy costs and emissions.

Heat Pumps Guide

Choosing a heat pump is not really a question about one appliance. It is a question about your whole heating system: how much heat your home loses, how your radiators or underfloor heating deliver warmth, where the equipment can go, how hot water is stored, what grants apply and whether the installer designs the system Read more »

Most problems start small: blocked airflow, dirty filters, poor pressure, incorrect settings, vegetation around the outdoor unit, or a service requirement that gets missed until performance drops. The good news is Read more »

How to Defrost a Heat Pump

Heat pumps are often covered by snow during the winter months. The pump may not work efficiently when its coil is covered by white frost or ice. When the entire unit is iced-up during the winter season, it may seriously damage the unit and reduce its life expectancy. You need to address this issue without Read more »

Best Heat Pump Brands

Choosing the right heat pump brand is one of the most important decisions you’ll make when installing a renewable heating system. The brand affects not just upfront cost but long-term reliability, efficiency ratings, installer availability, and how easy it is to get serviced when something goes wrong ten years down the line. This guide covers Read more »

About Geothermal Energy Technology

Geothermal energy technology uses heat stored beneath the ground. In UK homes, that usually means shallow geothermal systems such as ground source heat pumps. At a larger scale, it can also mean deep geothermal projects that use hotter rocks or groundwater for heat networks and, in some locations, electricity generation. The distinction matters.
