What are the best renewable heating solutions?

One of the most common questions from our customers is which option is the best renewable heating solution. The best renewable energy option for your property will depend on your budget, property space, and how much money you want to save on energy bills.

Although there is no one-size-fits-all solution when it comes to renewable energy, the following renewable heating solutions provide you with a comprehensive range of benefits:

Heat Pumps

Heat pumps absorb heat from the environment to produce hot water to heat your home. 

They work by absorbing the heat from the environment and transferring it to a fluid, which is compressed to increase its temperature. This heat is then transferred into the central heating system, to use for both heating and hot water.

There are two types of heat pumps: air-source heat pumps and ground source heat pumps. 

The main difference between air-source heat pumps and ground source heat pumps is that air-source heat pumps absorb heat from the air whereas ground source heat pumps absorb heat from the ground. 

Air Source Heat Pumps

An air-source heat pump is an electrical device that heats your home in an energy-efficient way. Air-source heat pumps extract heat from one place and transfer it to another. 

This renewable heating solution uses a refrigerant system involving a compressor and a condenser to absorb heat. This heat is then circulated around the home through a central heating and hot water system. Furthermore, air-source heat pumps can also operate for cooling too.

Air Source Heat Pump

What are the advantages of air-source heat pumps?

Air-source heat pumps have several advantages. These include:

  • Reduced carbon footprint by using a renewable energy source
  • Cheaper to run than traditional alternatives
  • Ideal solution for underfloor heating
  • Can be used to provide cooling in the summer months
  • Little maintenance required
  • Compact in size and highly efficient
  • This renewable heating solution is included in the Renewable Heat Incentive

Ground Source Heat Pumps

Ground source heat pumps extract thermal energy from the ground near your property and convert this energy into heating for your home and hot water. 

Ground source heat pumps use a simple renewable heating system through the use of pipes.

How do ground source heat pumps work? 

To put it simply, a pipe with a fluid called TTF (Thermal Transfer Fluid) is placed outside your property. The heat from the ground is easily absorbed into the fluid. Subsequently, this heated fluid goes through a process called Heat Exchange, which heats your home’s water.

Ground source heat pumps are designed to work in cold temperatures which is ideal for homes in the UK.

Ground Source Heat Pump

What are the advantages of air-source heat pumps?

Ground source heat pumps have several benefits. These include:

  • Reduced carbon footprint by using a renewable energy source
  • Heats your home and hot water
  • A great solution for underfloor heating
  • Can be used with your existing heating system
  • Options for homes with limited space
  • This renewable heating solution is included in the Renewable Heat Incentive

Biomass Heating

Biomass provides all your heating and hot water, with a clean, sustainable fuel eliminating the requirement for fossil fuel. Biomass boilers burn wood pellets, from sustainable sources and create an environmentally friendly carbon cycle.

The UK Government also recognises the benefits of Biomass and to encourage installations, are offering generous payments through the Renewable Heat Incentive (RHI). 

Modern Biomass boilers are almost completely automated, requiring only an annual service. Simple heating controls run the heating and hot water just as a conventional system.

Biomass systems can work in most properties and they replace completely gas boilers and oil boilers. They can be connected to existing heating systems with minimum disturbance.

Biomass boiler heating

What are the advantages of biomass boilers?

Biomass is a modern solution for lower fuel costs and reduced emissions. Their benefits include:

  • Reduced carbon footprint by using a renewable energy source
  • A viable alternative when replacing or installing an oil boiler, LPG, or gas boiler
  • A great solution for underfloor heating
  • Can be used with your existing heating system
  • Switching to Biomass gives independence from fluctuating energy prices
  • UK-sourced wood fuel supports local businesses and the rural community
  • Reduced storage and security costs of fuel as opposed to oil boilers and LPG
  • This renewable heating solution is included in the Renewable Heat Incentive

A-Rated Boilers

Heating your home, particularly during the colder winter months, can make up more than half of your energy bills. 

However, an A-rated boiler will get maximum heat energy out of the fuel it burns, lowering heating bills and minimising carbon emissions. 

Therefore, replacing an old inefficient boiler with a new modern reliable condensing boiler will improve efficiency to over 90%, thus saving you a minimum of 30% per year on your home heating bills.

Different Types of A-Rated Boilers

There are a number of A-rated condensing boilers, including Worcester Bosch, Glow Worm, and Vaillant.  

Getting the right boiler installation for your home will depend on a number of factors, such as the size of your property, number of rooms, energy source, and the location of the replacement boiler. 

Subsequently, this is why we recommend having a free boiler quotation with one of our boiler specialists. Our customers benefit from having the best advice so that they can make informed decisions.

What are the benefits of installing an A-rated boiler?

There are several benefits to having a modern a-rated boiler in your property:

  • Reduced energy bills
  • Reduced carbon emissions
  • Long warranties and durability
  • Low maintenance
  • A-rated modern boilers are often smaller, freeing up valuable space in your property.
  • Potential benefits from the government supported schemes and grants

Smart Heating Controls

Smart heating controls are internet-connected programmable controls for central heating and hot water.

The smart heating controls link up to the boiler to improve efficiency and reduce the amount of wasted heat by having better control. Furthermore, users can operate heating remotely by using devices such as a smartphone, tablet, or PC.

Smart heating controls are a great renewable energy heating solution as they allow you to control your home energy consumption better, lowering the demand on your energy bills and lowering your carbon footprint.

Homeowners who have a requirement for controlling the heating remotely will benefit most. For example, if you are caring for a less-abled or elderly person, travel frequently and forget to turn your heating off or rent a property that requires the heating to be switched off in-between tenants. 

Most noteworthy, the smart heating controls are excellent for remotely turning up your heating so that you arrive back to a nice warm house.

  • Reduced energy bills
  • Reduced carbon emissions
  • Operating heating remotely via mobile phone, tablet, or PC
  • Low maintenance
  • Perfect for holiday homeowners, those that travel or care for elderly relatives

Renewable Underfloor Heating

The Energy Saving Trust (EST) claims that underfloor heating is more effective than radiators and therefore can reduce both your energy bills and carbon footprint.

A water-fed system is where a series of pipes is channelled under the floor and are connected to your boiler to circulate warm water. 

This system is best suited to new floor constructions so it can be designed to hold the pipework effectively and ensure the heating doesn’t escape downwards. However, it can also be installed under existing floors.

Having an underfloor heating installation is a popular choice where a kitchen or bathroom has tiles or wood flooring. However, you can use this heating system under the carpet and throughout the whole property.
