MVHR (Mechanical Ventilation & Heat Recovery)
Full MVHR system design for homes across West Sussex & Hampshire — working in harmony with your heat pump and underfloor heating for a warmer, healthier home.
What Is MVHR & How Can It Benefit Your Home?
Fresher Air, Less Heat Loss — A Smarter Way to Ventilate Your Home
Mechanical Ventilation with Heat Recovery — known as MVHR — is a whole-house ventilation system that continuously supplies your home with fresh, filtered air whilst simultaneously recovering up to 95% of the heat that would otherwise be lost through conventional ventilation. Rather than simply extracting stale air and replacing it with cold air from outside, an MVHR unit draws the outgoing warm air across an internal heat exchanger, transferring that warmth into the incoming fresh air supply before it enters your living spaces. The result is a home that is constantly ventilated with clean, fresh air — free from moisture, allergens, and pollutants — without the heat loss and energy waste associated with opening windows or running traditional extractor fans. At Clean Heat Solutions Limited, we provide full MVHR system design and installation for homeowners across West Sussex and Hampshire, with every system carefully designed to complement your air source heat pump and underfloor heating for a complete, high-performance renewable heating and ventilation solution.
Our Process
How It Works
System Design & Ductwork Planning
We begin with a detailed assessment of your property, calculating your ventilation requirements room by room and designing a full ductwork layout that ensures clean, fresh air reaches every part of your home efficiently and quietly — with no cold spots and no compromise on comfort.
Installation & Ductwork
Our engineers install the central MVHR unit — typically in a loft, utility room, or plant room — and run the carefully designed ductwork network throughout your property, connecting supply and extract valves in all key rooms to ensure a continuous, balanced flow of fresh air throughout your home.
Commissioning & Balancing
Once installation is complete, we commission and balance the system to ensure the correct airflow rates are achieved in every room, the heat recovery unit is operating at full efficiency, and your home's ventilation is performing exactly as designed before we hand over and walk you through how to get the most from your system.
Benefits
Why Choose MVHR (Mechanical Ventilation & Heat Recovery)
Recover Up to 95% of Lost Heat
Rather than losing warm air every time your home is ventilated, MVHR captures and recycles that heat energy — significantly reducing the demand on your heat pump and keeping your energy bills as low as possible throughout the year.
Cleaner, Healthier Indoor Air
MVHR continuously filters incoming fresh air, removing dust, pollen, pollutants, and allergens before they enter your living spaces — making it an outstanding choice for households across West Sussex and Hampshire where air quality and family health are a priority.
Works in Perfect Harmony With Your Heat Pump
Designed to complement air source heat pumps and underfloor heating systems, MVHR reduces the overall heat demand of your property — allowing your heat pump to operate more efficiently, more consistently, and at a lower cost all year round.
MVHR is particularly well suited to modern, well-insulated homes and properties that have undergone significant retrofitting work — the more airtight a property becomes, the more important it is to have a controlled, efficient ventilation strategy in place. Without it, moisture and stale air can build up, leading to condensation, damp, and poor indoor air quality. MVHR solves this entirely, providing a constant supply of fresh, tempered air without the heat loss that comes with opening windows or relying on passive ventilation. When combined with an air source heat pump and underfloor heating, MVHR completes the picture — your heat pump generates the energy efficiently, your underfloor heating distributes it evenly, and your MVHR system ensures that warmth is retained and your indoor environment remains comfortable, healthy, and fresh throughout the year. It is the final piece of a truly high-performance home heating and ventilation system, and our Heat Geek Elite approved engineers will design every element to work together seamlessly across West Sussex and Hampshire.
We provide full MVHR system design as part of every installation — including duct routing, airflow calculations, and full integration with your heat pump and underfloor heating system — so every element is specified to work together from day one.
FAQ
Frequently Asked Questions
MVHR is most commonly installed in new builds due to the ease of integrating ductwork during construction, but it can absolutely be retrofitted into existing properties. The feasibility will depend on your property's layout and the space available for ductwork runs and the central unit. Our engineers will assess your home and advise you on the most practical and cost-effective approach for your specific property.
