Heat Pump Installation in SE1 Apartments: What You Need to Know

Did you know you could qualify for £7,500 a government grant by replacing an old oil or gas boiler with an efficient heat pump? But before you jump in, it's worth understanding if a heat pump is the right fit for your home. We'll cover everything you need to know about heat pump installation in SE1 apartments to help you decide.

 

Why should you install a heat pump?

 


Heat pumps work by extracting heat from the air, ground, or water around your home and then using this heat to efficiently warm your flat. Because they use this readily available and renewable source, heat pumps are a clean energy option and tend to produce less carbon emissions than traditional boilers — perfect if you are looking for ways to lower your carbon footprint. What’s more, heat pumps can help lower your heating costs over time.

 

Compact heat pumps for SE1 apartments

Gone are the days when heat pumps were meant only for traditional houses. It’s now possible to install them in flats.

 

However, flat installations can be more complex, so be sure to work with a Gas Safe registered heating engineer. They'll handle the installation properly and help you select the right heat pump for your SE1 flat. For example, a typical one-bedroom flat usually needs a more compact unit — either an air-source or ground-source heat pump would likely be suitable. Your Gas Safe engineer can make recommendations.

 

Air-source heat pumps vs ground-source heat pumps

Air source heat pumps use the outside air to heat your SE1 apartment and provide hot water. Their ability to function even in very cold temperatures (down to -15 degrees Celsius) is their key advantage.

 

Ground source heat pumps, on the other hand, extract heat from the ground, so they are well-suited for heating systems like underfloor heating, radiators, and hot water. They’re also often a good choice for heating an entire block of flats.

 

Which heat pump is right for your SE1 flat?

Because apartments typically have less space to heat than a house, a smaller air source heat pump is usually sufficient for an individual flat in SE1.

Air source heat pumps work well for apartments, especially if you have at least one square meter of outdoor space. However, if you have a small balcony, you'll want to consider whether you're willing to give up some of that space for the heat pump unit.  If your flat doesn't have a balcony, the unit can often be installed on an exterior wall.

 

Installing a heat pump in a shared space

There needs to be sufficient outdoor space for a block of flats to use a shared ground source heat pump system. Ground source heat pumps are often a good fit for these types of buildings. 

 

The amount of land required depends on how much heating is needed and the specific heat pump system chosen, but as a general rule, you'll need about 2.5 times the building's total floor area in surface area. Once the shared ground loop system is installed, the part that draws heat from the ground is buried nearby and then connected to individual heat pump units inside each flat.

 

SE1 building regulations that can impact your heat pump installation

If you own the freehold to your property, installing an air-source heat pump is usually considered permitted development, meaning you typically won't need planning permission. Ground-source heat pumps are also generally permitted development for freeholders. With ground-source systems in blocks of flats, each apartment usually has its own indoor unit, and residents are billed individually for their electricity usage.

 

Do you need to make major changes to your SE1 apartment to accommodate a heat pump?

You likely won't need to do any major renovations to your SE1 flat to install a heat pump. Heat pumps are at their best when they're steadily providing gentler, lower-temperature heat, and to really get the most out of them, it's important to keep heat loss to a minimum. Flats often have an advantage here as they tend to be better insulated than houses (because they share walls with other units). Having a bit of private outdoor space (like a balcony) also simplifies the heat pump installation process.
