Upgrading your heating system

Installing a new, modern heating system at home doesn’t need to be a lengthy process, it can take as little as three days with your local Vaillant heating installer.

When it comes to replacing your heating system, it is worth considering whether you are looking to move to a new heating source, or whether you wish to continue with your current heating source.

Looking to replace a gas boiler?

Switching to a modern high-efficiency combination, system or regular boiler from Vaillant, has significant benefits when it comes to operating costs and has a reduced impact on the environment. Our condensing boilers utilise the heat in the flue gas, resulting in an energy efficiency of up to 98% and can result in reducing your fuel consumption by up to 30% when compared with an older system.

Using renewables to save money and cut carbon

Older gas, oil and electric boilers work inefficiently and emit too much CO2, and the continual rise in fuel prices leads to greater running costs. Renewable heating systems enable you to utilise renewable energy and ultimately save on fuel costs.

Are renewables suitable for period homes?

A popular option is to combine a boiler with a solar thermal system and/or a hybrid heat pump. This option is favoured by homeowners who have large period homes that may be grade listed, as often these types of buildings are not as well insulated and efficient as a modern home. We recommend making improvements to the fabric of the building where possible and permitted, but combining renewables with a traditional heating system can be a viable option to compensate for possible restrictions or limitations when updating a period home. It is always best to consult a reputable installer to understand the benefits of a hybrid system compared to switching to renewables completely. An installer will be able to outline the cost of the installation, how much energy and carbon you are likely to save, how much money this will save you on your energy bills and whether you will be eligible for Government payments, such as RHI.

Are renewables suitable for modern homes?

Modern homes are usually built with insulation and efficiency in mind. Compared to period homes, a modern home will be better insulated to preserve heat, reduce drafts and reduce the risk of damp. This is a good starting point to be considering the switch to renewables as your home is already efficient and will help to maximise the gains achieved from adopting a heat pump and/or solar thermal system. If you live in an off-gas area and rely on fossil fuels to heat your home and generate hot water, then it is worth assessing whether adopting a hybrid system or fully switching to renewables is best for your home. A reputable installer will be able to help outline the costs of installing a hybrid system or switching to a fully renewables system, as well identify how much energy, carbon and money you could save. An installer will also be able to advise you on whether you will qualify for the Government RHI payments.

Saving money with solar

Solar water heating systems, or solar thermal systems, use thermal energy from the sun to generate hot water and heating for your home. Solar thermal systems can be used with modern heating systems, and will help to cover about 60% of your hot water and 20% of your heating needs. You could also benefit from Government subsidies thanks to Vaillant solar thermal systems being MCS accredited.

Saving money with a hybrid heat pump

Hybrid heating solutions work by combining a heat pump with a traditional heating technology, such as a gas boiler. Hybrid systems generate both heating and hot water for your home and can help to significantly reduce your energy bills and CO2 emissions. Hybrid heat pumps are compact and a great solution for those looking to upgrade their current heating system, but want to focus on reducing running costs and introducing renewable and sustainable technology to the home.

Our hybrid heat pumps are MCS accredited, which means they could qualify for Government subsidies.

Completely switching to renewable energy for greater savings

Adopting renewable technology, such as heat pumps, is a great option for homeowners who have already adopted renewable technology like solar PV. However, heat pumps are also great for homeowners looking to replace their heating system with something modern and sustainable that will help to save on fuel bills.

Heat pumps save have low running costs, reduce your impact on the environment and in many cases, you can also benefit from government subsidies thanks to Vaillant heat pumps being MCS accredited.
