HEAT PUMPS


Solid Renewables offers solutions using air, ground or water source heat pumps.

Heat pumps are simple to install, cost effective and offer outstanding energy efficiency. The technology offers a low carbon alternative to traditional boilers in modern buildings. The typical payback time if the technology is correctly sized in a well-insulated building is 5 years



The benefits of heat pumps

  • Could lower your fuel bills, especially if you are replacing conventional electric heating
  • Could provide you with an income through the government’s Renewable Heat Incentive (RHI)
  • Could lower your home’s carbon emissions, depending on which fuel you are replacing
  • Don't need fuel deliveries
  • Can heat your home and provide and hot water
  • Need little maintenance - they're called ‘fit and forget’ technology

Ground source heat pumps

We believe that heating systems using ground source heat pumps to provide all your hot water and heating needs (without requiring expensive, regular maintenance checks and which are safer than traditional, volatile, fossil fueled heating systems) are the future of heating in the UK.

What are ground source heat pumps?

Ground source heat pumps are renewable energy products which use stored solar energy or ‘ground source heat’ to provide heating and hot water as an alternative to dangerous and expensive fossil fuels.

How do Ground Source Heat Pumps work?

There are many heat pump misconceptions which can sometimes leave people feeling confused as to how ground source heat pumps work. However, put simply, this type of heating pump moves stored solar energy, sometimes referred to as ground source heat, into the home to provide a total solution for domestic hot water and all heating needs.

Heat Pump Ground Collector

Different options are available for the installation of the pipework or Ground Loop which collects the stored solar heat used by heat pumps. These include Slinky and Straight Ground Loops, where the pipes are laid in trenches beneath the ground, or alternatively – when space is at a premium – there is the added option of using boreholes.

Air source heat pumps

While ground source heat pumps offer greater efficiencies over air source heat pumps, the ground source solution is not for everyone, often due to space considerations or the required ground works for heat pumps. As a result, many people wrongly believe they are better off retaining their existing heating system. In fact, air source heat pumps can save you hundreds of pounds on your annual running costs, with minimal installation disruption.

What are Air Source Heat Pumps?

Air source heat pumps are renewable energy products which extract heat from the air to provide a total solution for domestic hot water heat which can be distributed via underfloor heating systems, radiators.

It’s worth remembering that to get the most efficiency from your heat pump, it pays to make your home as well insulated as possible. Less well insulated homes may not achieve the highest COP levels. COP levels will also depend on the emitter system (radiators, etc) installed.

Exhaust air heat pump (EAHP)

An Exhaust Air Heat Pump (EAHP) extracts heat from the exhaust air of a building and transfers the heat to the supply air, hot tap water and/or hydronic heating system (underfloor heating, radiators). This type of heat pump requires a certain air exchange rate to maintain its output power. Since the inside air is approximately 20-22 degrees Celsius all year round, the maximum output power of the heat pump is not varying with the seasons and outdoor temperature. The exhaust air heat pump can cope with a maximum of 4 KW heat load that correspond to 100 to 120sqm new build in accordance to building regulation.

How do Exhaust Air Heat Pumps work?

Unlike a conventional heat pump, which converts energy from the ambient air, ground or water, exhaust air heat pumps recover the energy from the ‘exhaust air’, extracted from well-insulated, air-tight homes, and use it for central heating and domestic hot water. Once the heat pump has extracted the energy it needs from the recovered warm stale air, the used cold air is released outside. Fresh air is then drawn back into the building to provide the property with sufficient ventilation – allowing for healthy buildings and residents and preventing issues like damp and mould.

The energy contained within the exhaust air is influenced by three distinct factors:

  • The natural temperature of the outside air entering the building via the wall vents
  • Warmth added by the home’s heating system (the exhaust air heat pump)
  • Warmth added as a result of human activity and appliances within the home

Our Domestic Service

We offer a full design and installation service for solar panels, tiles or slates – as appropriate - from 1.0kWp right up to 4.0kWp systems on a single phase, or up to 17.0kWp on a three phase system.

An initial consultation will enable us to fully understand our customers’ individual requirements, after which we will be in a position to recommend a bespoke solution to fit in with your property and budget limitations.

You will be provided with a report clearly illustrating projected annual savings and income, set against up-front installation costs – enabling you to be comfortable with the decisions you make.

As with all Solid Renewables projects, we will keep you fully informed all the way through the design, installation, commissioning and handover process; using only fully qualified and accredited staff.

We aim to exceed our customers’ demands and requirements and all contractors/staff have sound training to install our systems; every installation is undertaken to the highest standard.

Our Commercial Service

Saving you money in the short-term, making you money in the long-term and helping you to meet business sustainability targets – investing in solar just makes good commercial sense.

We can work with your business directly, taking the installation all the way from design to delivery, or join you at a particular stage of your project. Our service covers:
