Heat pump installations across South London and Surrey

Heat pumps offer an efficient, sustainable alternative to traditional gas and oil boilers.

By extracting renewable energy from the air or ground, they provide reliable heating while significantly reducing your carbon footprint and energy bills.

Lower Energy Bills

Heat pumps typically produce 3-4 units of heat for every unit of electricity used, making them significantly more efficient than conventional heating.

Eco-Friendly

By using renewable energy sources and producing zero on-site carbon emissions, heat pumps help reduce your home's environmental impact.

Air source and ground source heat pumps

There are two main types of heat pump systems most homeowners ask about.

Air source heat pumps - Air source heat pumps take warmth from the outside air and transfer it into your heating system. They’re often the most practical option for residential properties because installation is generally more straightforward than ground source systems.

Ground source heat pumps - Ground source heat pumps collect heat from the ground through buried pipework. They can be highly efficient, but they usually require more outdoor space and a bigger installation project overall.

For many homes in Sutton, Surrey and South London, air source heat pumps are the most realistic option, but we can advise based on the layout and needs of the property.

Is a heat pump right for your home?

Insulation levels : The better insulated the home, the better a heat pump is likely to perform. Homes with good insulation, modern windows and fewer draught issues tend to get the best results.

Existing heating system : Heat pumps operate differently from gas boilers, so it’s important to consider how they’ll work with your radiators, pipework, hot water cylinder and controls.

Available space : Outdoor unit placement, indoor cylinder space and access all need to be looked at properly before installation.

Heating expectations : Heat pumps provide steady, efficient heating over time. They suit homes where the system can run consistently rather than being pushed to heat up very quickly in short bursts.

Why more homeowners are considering heat pumps

Heat pump installation done properly

A heat pump installation isn’t just about fitting the unit itself. The wider system matters just as much. Pipework, emitter sizing, controls, hot water setup and general system design all need to work together if you want the heat pump to perform as it should.

That’s why we take a practical approach from the start. We look at the property, the current heating setup and what you actually want from the system. In some cases, a heat pump is a very good fit. In others, changes may be needed first, or a different heating route may make more sense.

Heat pump repairs and ongoing support

We don’t just install heat pumps. We also help diagnose faults and carry out repair work where systems are not performing as they should. That might involve issues with controls, circulation, system pressure, hot water production or general performance problems.

If your system is showing fault codes, struggling to maintain temperature, or simply not running as expected, we can inspect the setup and advise on what needs attention.

Heat pump servicing and maintenance

Like any heating system, a heat pump needs regular maintenance to keep it running efficiently and reliably. Servicing helps identify wear, keeps performance on track and reduces the risk of unexpected faults.

Routine servicing may include checking system pressures, cleaning filters, inspecting electrical connections, reviewing controls, checking refrigerant-related operation and making sure the wider heating system is working properly alongside the heat pump.

Heat pumps and hot water cylinders

Most heat pump systems work alongside a hot water cylinder, so cylinder condition and sizing are important. If your current cylinder isn’t suitable, that may need to be addressed as part of the installation.

We can also advise on unvented hot water cylinders where required, making sure the full system is designed to deliver reliable heating and hot water rather than just focusing on one part of the job.

Straightforward advice on heat pump options

A lot of homeowners are interested in heat pumps but aren’t sure where to begin. That’s understandable. There’s a lot of information around, and not all of it is clear or relevant to your specific home.

At RCB Plumbing Ltd, we keep it practical. If a Samsung, Vaillant, Daikin, NIBE, Mitsubishi Electric, Viessmann or Grant system looks like a good fit for your property, we’ll explain why. If changes are needed first, we’ll tell you that too. The aim is to help you choose a heating system that works properly in real life, not just on paper.

Frequently Asked Question

How do heat pumps work?

Heat pumps extract warmth from the air or ground using a refrigerant cycle, similar to how a refrigerator works but in reverse. This renewable energy is then transferred to your home's heating system.

Are heat pumps suitable for all properties?

Most properties can benefit from heat pumps, but factors like insulation levels, existing radiator sizes, and available outdoor space can affect suitability. Our engineers conduct thorough assessments to determine if your property is suitable.

How much can I save with a heat pump?

Savings vary depending on your current heating system, energy prices, and home insulation. Many customers see 30-50% reductions in heating costs compared to traditional systems.

Do heat pumps work in cold weather?

Yes, modern heat pumps are designed to operate efficiently even in sub-zero temperatures. Air source heat pumps can extract heat from air as cold as -25°C.

What maintenance do heat pumps require?

Heat pumps need annual servicing to ensure optimal performance. Our service includes checking refrigerant levels, cleaning filters, inspecting electrical connections, and verifying system pressure.
