Types of Heat Pumps

Heat Pump Installers

Air-Source Heat Pump (ASHP)

Air Source Heat Pumps draw warmth from outdoor air for indoor heating and are prevalent in temperate climates. An Air-Source Heat Pump (ASHP) is a heating and cooling system that moves heat between indoor and outdoor air. During winter, it extracts warmth from outside air and transfers it indoors for heating, whilst in summer, it removes heat from indoor air and moves it outdoors for cooling. ASHPs are energy-efficient and can reduce homeowners' heating and cooling costs. However, their performance may be impacted by extreme temperatures, and they might not be suitable for all climates.

Dual-Fuel Heat Pump System

Dual-Fuel Heat Pumps merge an electric heat pump with a backup heating source that alternates based on outdoor temperatures. This hybrid system combines an electric heat pump with a gas boiler, automatically switching between the two to deliver the most efficient and cost-effective heating solution. When outdoor temperatures are mild, the heat pump handles heating and cooling, whilst the gas boiler takes over when temperatures plummet below a certain threshold. This setup is particularly well-suited for regions with harsh winters, as it ensures effective heating even in extreme cold. However, it may not be the ideal choice for areas with steep electricity or gas costs. The system's ability to adapt to temperature changes makes it a versatile option for many homeowners.

Ductless Mini-Split Heat Pump

As the name implies, this system requires no ductwork, with the outdoor unit linking to separate indoor units for zoned temperature control. It comprises an external compressor unit and one or more internal air-handling units affixed to walls or ceilings. The indoor units connect to the outdoor unit via a small conduit housing the refrigerant line, power cable, and condensate drain. The system offers both heating and cooling, with independent control in each room or zone. Ductless mini-split heat pumps are energy-efficient, potentially reducing homeowners' heating and cooling costs. They're particularly suitable for homes lacking ductwork or for room extensions where expanding existing ductwork isn't practical. However, installation costs can exceed those of traditional HVAC systems, and the indoor units may appear bulky and unattractive.

Air-to-Water Heat Pump

Air-to-Water Heat Pumps extract warmth from outdoor air and transfer it to a water-based heating system, suitable for homes and businesses alike. This heating method moves heat from the air outside to water, which then warms radiators, underfloor heating, or a hot water cylinder. The setup includes an outdoor unit housing a compressor and heat exchanger, plus an indoor unit with a pump and heat exchanger. By reversing the refrigerant flow, the system can also cool during summer months. Air-to-Water Heat Pumps offer energy efficiency, potentially reducing heating costs for homeowners. They're particularly useful for properties without access to mains gas or propane heating. However, these systems may struggle in extremely cold climates, and their installation can be pricier than conventional heating and cooling systems. Despite this, their eco-friendly operation and potential long-term savings make them an attractive option for many households seeking sustainable heating solutions.

Andrew installed a new boiler, four new radiators and replaced another four radiators. The style and quality of the radiators you recommended were amazing. The new radiators required extensive chasing for the pipes Andrew arranged for the walls to be made good with excellent plasters and decorators. He has a great work ethic and an equally professional team of tradesmen to support him. The work was completed within two weeks just before Christmas. We were amazed and very appreciative, I would thoroughly recommend Andrew to anyone for their Heating and plumbing needs.

I’d like to give this company a big thumbs-up for their service. I called them on Sunday, and even though it was just a few days before Christmas, they confirmed a time right away and came on Monday to handle the water leak detection. Andrew was super professional, fast, and kept me updated the whole time, giving me real peace of mind. They pinpointed the problem quickly and did a fantastic job. Honestly, their service was just unbeatable. Highly recommend them!

I can not recommend Andrew and his work more highly - I was in a pickle with a leaking hot water tank, damage to the lounge ceiling going on holiday in 5 days. Because of an old traditional boiler, I went for a combo boiler replacement which involved moving the boiler upstairs into the airing cupboard, freeing up a lot of space. Fitting took Andrew 5 hours on Saturday and 8 hours on Sunday (whilst we were out watching West Ham beat Newcastle) and then a few hours Wednesday finishing up. So I got away with a working new system and the lounge ceiling drying out for later work. THANK YOU ANDREW!

We knew we had a few problems with our central heating after 25 years in our home. Losing pressure every day and poor hot water, it was a challenge to find the leaks with concrete floors. Andrew did find two leaks and fitted a new water boiler, along with a few upgrades elsewhere. I now have consistent heating and hot water throughout my home.

Andrew was always very helpful and pleasent to deal with.

Andrew was exceptional. So helpful and professional and after previously using a large company that sent more than 7 different engineers each diagnosing something different with my boiler, having an owner operated business was a breath of fresh air.
Cannot hesitate to recommend and will only use South Thames Maintenance in future. Lovely to have a full working boiler!

Leaving reviews when you have bananas for fingers can be awkward, but sometimes a company deserves the 5 stars and South Thames Maintenance Services did a great job replacing my boiler. When other companies failed to call back, Andrew, from STMS returned my call and was on hand within a day. He diagnosed the problem and clearly gave me options, with the no brain solution being a new boiler. Again, options were discussed and on the next working day my old Valiant boiler was replaced with a Glowworm. Andrew worked with respect to our property, laying carpet coverings. He was friendly and polite and our dog, a great judge of character, liked him. Thanks for a good job well done.
