As we strive for energy-efficient, sustainable and healthy homes, Mechanical Ventilation with Heat Recovery (MVHR) systems have gained in popularity
For anyone aiming for a Passivhaus certified build, then an MVHR system is a necessity to maintain the quality of indoor air. But how much does MVHR cost? These systems play a crucial role in maintaining a healthy indoor environment by providing fresh air while recovering heat from the outgoing stale air. In the long run, a well designed and correctly installed system can save you money on the cost of heating your home.
If you’re considering installing an MVHR system in your new build house or as a retrofit project, the cost depends on a number of factors which we will explore below. One of the most important things to remember is to plan for your heat recovery system as early in your project as you can to help keep your budget in check.
Factors influencing the cost of MVHR
House Size and Layout:
The size and layout of a house will significantly impact the design and cost of installing an MVHR system. The number of rooms and floors within the property will affect the complexity of the installation process.
Design and Complexity:
The design and complexity of the property will play a crucial role in determining MVHR system costs. Architectural styles, building materials, ceiling heights, and structural considerations will all impact the installation process. Ducting routes will need to be considered as early as possible in the design stage of your overall project, ideally at the architect’s stage so that ducting and sufficient plant provision is included.
Engaging with an MVHR installer as early as possible in your project could help save you money in the long run as ducting routes can be planned for in the most efficient way – both from an installation point of view and also to increase the running efficiency of your system for its lifetime.
Equipment and Components:
The cost of an MVHR system can vary based on the specification of the system, and of the components used. Higher-end systems often offer advanced controls, energy-efficient motors, and filters with better air purification capabilities. While these systems may come at a higher initial cost, they can provide long-term savings through improved energy efficiency and enhanced indoor air quality. Dantherm MVHR units come with a VOC (Volatile Organic Compounds} sensor as standard.
Installation and Labour:
It is crucial to hire qualified HVAC contractors experienced in installing MVHR systems to ensure the correct installation. If undertaking the project yourself you may save money on the design and installation however, you may make mistakes which could drastically reduce the efficiency of your system, or leave you with a noisy or faulty system. Complex installations, large buildings or retrofitting in existing buildings may involve more labour hours which will also increase the project price.
Here we will look at how much an MVHR system could cost for a typical 3-bedroom new-build family house.
Example cost of MVHR for a 3-bedroom new build house
Considering the various factors that contribute to the cost of an MVHR project, let’s look at a hypothetical cost breakdown for installing an MVHR system in a typical 3-bedroom new build house:
Equipment and Components
On average, a Dantherm MVHR system for a 3-bedroom house will cost less than £2200.00, unit list price. This is a passive house certified unit.
Ductwork and Fittings
The cost of ductwork and fittings can vary based on the building layout and complexity. For a typical 3-bedroom new build house, the estimated cost can range from £1,500 to £1,900*.
Controls and Accessories
Dantherm MVHR units come with all the controls and sensors as standard for a domestic installation.
Installation and Labour
The installation cost varies depending on the location and complexity of the project. For a typical 3-bedroom new build house, the installation cost can range from £1,500 to £2,300*.
Design and commissioning
Initial design cost is around £270 to £365 with final commissioning and Building Control certification being £360 to £500.
Total Estimated Cost
Taking all of these factors into account, the total cost for installing an MVHR system in a typical 3-bedroom new build house can range from £7,800 to £8,600*.
MVHR installation costs
MVHR costs can vary depending on the size and complexity of your home, the type of system you choose, and the cost of installation. However, in general, MVHR can be a cost-effective way to improve your home’s indoor air quality and save money on your heating bills.
