Every air-to-water heat pump installation needs a cylinder, because there is no heat pump equivalent of a combi boiler that heats water instantly. If you have a combi now, the main design question is where the cylinder will go. If you already have a cylinder, it will almost always need replacing with a heat pump model, though the same cupboard can often be reused if it is large enough.
Cylinder sizes for Angus and Dundee homes are based on the people living there and the bathrooms in daily use. In terraced homes around Angus and Dundee and across Angus and Dundee, slimline cylinders can fit spaces a standard model cannot. Discharge pipe routes are planned at the survey so an Angus and Dundee cylinder can drain safely to the outside.
Who it suits
- Every air-to-water heat pump installation, whatever the existing boiler
- Households with older vented cylinders and loft tanks who want mains-pressure showers
- Homes with solar PV that want to store daytime electricity as hot water
- Homes replacing a combi boiler that need space found for a cylinder
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a home in Angus and Dundee, apply and receive the written offer before the installation date is fixed.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your property at survey.

Heat pump hot water cylinders questions
Can I keep my existing hot water cylinder with a heat pump?
Usually not. Cylinders designed for boilers have a small coil that cannot transfer heat quickly at heat pump temperatures, so the water would reheat slowly and efficiency would suffer. A heat pump cylinder has a much larger coil. The new cylinder can often go in the same cupboard, though, if there is enough height and floor space.
Will I run out of hot water with a heat pump?
Not if the cylinder is sized to how your household uses hot water. Unlike a combi, hot water is stored, so very heavy use, such as several long showers back to back, can use up the stored volume before it reheats. Sizing for your busiest period, and timing reheats sensibly, avoids this for most homes.
Do I need good water pressure for an unvented cylinder?
Yes. An unvented cylinder runs at mains pressure, so it needs enough incoming pressure and flow to supply your taps and showers well. We measure your mains supply at the survey. If flow is low, options include a different cylinder type or an upgrade to the incoming supply pipe, which we explain before you commit.
Does a heat pump cylinder need servicing?
Yes. An unvented cylinder's safety devices should be checked every year, including the relief valves, the expansion vessel charge and the discharge pipework. This is normally done as part of the annual heat pump service, and it is often a condition of the cylinder manufacturer's warranty. Keep the cylinder paperwork with your heat pump handover documents.
