Storage Heaters

Electric storage heaters are becoming more and more of a low-carbon option, as renewable energy sources like wind and solar are connected to the National Grid to generate the electricity to run them.

There are electricity tariffs available from most energy companies that offer electricity at cheaper rates during the night (when there is typically less demand). The heat generated at night is stored inside the core of the heaters and released during the day, when you need it. As part of our service, our engineers will configure your storage heaters to generate and release heat to suit your household.

Storage heaters from Evolve meet the latest efficiency standards (which were made much stricter in 2018) and have higher heat retention rates, quicker heat release rates when you need it and better controls and programmers.

Costs & funding

As an accredited installer, we have access to various pots of funding that can make storage heaters FREE or low-cost for you. The funding comes from places such as energy companies, local authorities and government.

We’ll check what you’re entitled to when you contact us.

Generally, new storage heaters are replacing existing ones that are no longer efficient. New, modern storage heaters will perform much better, keep running costs down and ensure occupants are warmer and more comfortable.

Storage Heater FAQs

What is a storage heater?

A storage heater is an electrically-powered heat bank that stores thermal energy during the evening when electricity is available at a lower cost. The heaters then release the heat during the day, as required.

Why should I have my storage heaters replaced?

Modern storage heaters are far more efficient than old ones, so you could be paying more than you need for to heat your home.

How long do new storage heaters take to install?

Usually a day or two, depending on how many are being replaced

What prep do I need to do before storage heaters are installed?

We ask you to clear the space around the heaters so our technician can work safely. Plus, please make sure the route from your front door to the heaters is clear too. Our technician will be as clean as possible, laying down dust sheets if needed and will tidy up afterwards too.

How much do storage heaters cost?

It depends on how many and what you currently have. Call the office for an idea of price or book for a FREE home visit and we’ll come and take a look for you.
