The Cosy heating system
Cosy is the complete package: a heat pump, hot water cylinder, straightforward controls and up to four Cosy Pods to monitor the temperature and humidity of your home.
Together with our clever Octopus tech, it works effortlessly to warm up your home and hot water up to 4x more efficiently than a gas boiler.
The outdoor unit
The Cosy heat pump is designed to be installed and run incredibly efficiently. Unlike many heat pumps, Cosy uses the new natural refrigerant R290, which is better for the environment.
Hot water cylinder
Sized to suit your home, our hot water cylinders are highly insulated to keep heat loss to a minimum whilst storing your hot water. Made from durable duplex stainless steel.
Cosy Hub
This smart device sends information back and forth from your heat pump to your app. Built with handy light indicators to show connection, heat status and more.
The Octopus Energy App
Control your heating and water from anywhere, with ease. Switch heating on and off, set schedules, monitor temperature and humidity around your home, track your heating performance and much more.
How to get Cosy
The Cosy 6 heat pump is available today, and we plan to begin installing Cosy 10 in January 2025.
We'll calculate whether Cosy is the right fit for you by measuring your home's heat loss during your survey. If it's not the right fit, we'll match you with the perfect alternative heat pump from Daikin for the same price.

Frequently asked questions
Will Cosy work in my home?
Cosy 6 is suitable for homes with 1-4 bedrooms and heat loss of less than 5.6kW, while Cosy 10 is suitable for homes with 3-5 bedrooms and a heat loss of up to 9kW.
We will check this when taking our usual measurements during your survey. For more information on costs and installation requirements, check out our heat pump FAQs page.
Other considerations:
Do I need a hot water tank?
You'll still need a tank. A high temperature heat pump opens them up to a broader range of properties – can create the same temp as a gas boiler, so if a gas boiler heats your home today this will too.
Does the existing system have to be pressurised?
We'd recommend a pressurised system rather than open vented in some cases (the same applies to a boiler though!)
Does it work with microbore pipes?
A high temperature heat pump opens them up to a broader range of properties – can create the same temp as a gas boiler, so if a gas boiler heats your home today this will too.
Will the fan get blocked with snow?
We’ve worked closely with the fan manufacturer to ensure the mounting position isn’t affected by snow. In fact, the same designers worked on a RED heat pump model with a fan that sits and works directly upwards, installed across Scotland and Germany without any fan blockage issues.
What colour is Cosy 6?
Whilst the Cosy 6 was originally unveiled in purple, we are currently installing the model in dark grey with a hard-wearing mottled texture.
