Support with your heat pump after installation 

The part of the heat pump that sits outside is roughly 1m x 1m x 2m (or to help you visualise - the size of a moped). It needs a space of around a meter in front and to each side to breathe.

Inside you need space for a hot water tank - 2m x 1m x 1m (the size of a modern fridge freezer), on the ground or first floor of your home (the closer to the heat pump the better).

The cylinder can also be installed in a garage, outdoors in a purpose-built store, or in the loft, but this may decrease efficiency (it takes more energy to heat the water when the cylinder is exposed to the cold).

How much space do I need for a heat pump?

The Government is currently offering a £7,500 grant to UK homeowners - so there's not going to be a better time to get a heat pump.

To help suit your installation to your budget, at quote stage we'll provide two installation options: Cosy Turbo and Cosy Eco. A Turbo heat pump runs at a higher temperature and requires less plumbing changes, making it cheaper to install but more expensive to run. Whereas an Eco heat pump runs at a lower temperature and requires for more (or larger) radiators to be installed – costing a bit more to install, but less to run.

How much does a heat pump installation cost with Octopus Energy?

A heat pump is a super-efficient, all-electric heating system that pulls heat from the air outside – even when it’s freezing – to warm your home and provide hot water. It uses up to 4x less energy than a gas boiler, cutting carbon emissions and potentially 

Most homes can get one, especially if they’re well-insulated, and with the £7,500 Boiler Upgrade Scheme currently available, installation is more affordable than ever. Plus, heat pumps last around 20 years – nearly double the lifespan of a typical boiler.

If you want cleaner, greener heating (and to future-proof your home), a heat pump could be a brilliant fit!
