Finding the right cylinder for your heat pump.
Why the right cylinder makes a difference.
Your heat pump is the heart of your homes comfort, but it needs the right partner to perform at its best. A standard cylinder can hold it back, leading to inconsistent hot water and higher-than-needed energy bills. Upgrade to a heat pump cylinder (also known as a high recovery cylinder) to reach your heating system's full potential.
The perfect match
Does a heat pump need a hot water cylinder?
All heat pump types (air-source, ground-source and water-source heat pumps) require a hot water cylinder. The heat pump or high recovery cylinder works as a thermal store, efficiently storing the generated heat from your heat pump. This ensures you have a steady supply of hot water, even during busy times.
This not only enhances the performance of your heat pump, but also reduces energy consumption. This can also help to extend its lifespan and provide reliable heating and hot water for years to come.
Types of cylinders
Which cylinder suits your heating system?
- Closed system cylinders
These are perfect for homes with high hot water demand. This cylinder type delivers stable water pressure and installs almost anywhere in your home. With its sealed design, there's no need for a cold water storage tank.
- Open system cylinders
These are ideal if you have a traditional heating system with a cold water tank in the loft. They’re reliable and straightforward, making them a popular choice for many homes.
- Multi-function cylinder
These cylinders store heat and can supply both your heating and hot water needs. They’re versatile and can work with multiple heat sources, including your heat pump.
- Buffer tank
These are used to store excess heat generated by your heat pump. They help to balance the system, ensuring that your heat pump operates efficiently even during peak demand.
Efficiency
When is a special cylinder needed?
- When upgrading a heating system
- When looking for a new heating system
If you're upgrading from a boiler to a heat pump, you’re likely have a boiler cylinder already in place. However, it might not be suitable if you’re having a heat pump installed.
The right size
Choosing the right cylinder size.
| Household size | Cylinder size | Suggested heat pump |
|---|---|---|
| For small households (1-2 people) | 120-150 litre | 3kW |
| For medium households (3-4 people) | 170 - 200 litre | 7kW |
| For large households (5+ people) | 210 - 300 litre | 12kW |
Maintenance tips
How to look after your hot water cylinder.
- Regularly check for leaks
Keep an eye out for any signs of water around your cylinder. Early detection prevents bigger issues.
- Insulate your cylinder
A well-insulated cylinder retains heat better, saving energy and reducing costs.
- Schedule annual maintenance
Have a professional inspect your cylinder yearly. This ensures optimal performance in the long term.
- Bleed the air
So you have your cylinder for a long time.
