What is a Heat Recovery System?
Every home needs fresh air coming in and stale air going out. The trouble is, most ventilation methods, whether that’s opening a window or leaving a door on the latch, let all your heat escape in the process too. A heat recovery system gets around that.
It works by running two air streams past each other inside a unit. The stale air heading out of your kitchen or bathroom, and fresh air coming in from outside. As they pass, a heat exchanger pulls the warmth out of the outgoing air and passes it into the incoming air. The air itself doesn’t mix, just the heat. So the fresh air reaching your rooms has already been warmed up before it arrives, rather than blasting in cold the way it would if you’d simply opened a window.
That’s really all there is to it. Not a complicated bit of kit, just a smart way of not wasting heat you’ve already paid for.
Benefits of Heat Recovery Systems
Newer homes are built airtight. Good for keeping the heat in, not so good for letting moisture out. And that’s usually where the trouble starts with condensation on the windows, a damp patch behind the wardrobe, mould creeping into the corner of a bathroom that’s never had proper ventilation.
We see this constantly in newer builds, flat conversions, and older houses that have had double glazing or extra insulation fitted. It’s a bit of an irony really. The improvements meant to make a home more efficient can end up trapping moisture with nowhere to go. Heat recovery ventilation solves that by keeping air moving through the building all the time, so damp and stale air get dealt with before they become a problem rather than after.
There’s a cost saving in it too. Since incoming air is already warmed before it reaches your rooms, your heating isn’t working overtime just to bring the temperature back up. Over a full winter that adds up to a real difference on your bills, plus a house that just feels fresher to be in.
Our Heat Recovery Services
We design and fit heat recovery systems for homes and businesses across Bristol and the South West, and we don’t start with the unit. We start by looking at your property.
A one-bedroom flat and a five-bedroom house don’t need the same solution, so we won’t push you toward one. Some properties need a whole-house system covering every room. Others just need something targeted. A bathroom that never dries out, say, or a kitchen that steams up every time someone cooks. Once we’ve had a proper look, we’ll tell you which applies to your place, not just quote you whatever’s easiest for us to install.
From there our team gets on with fitting it, with as little upheaval to your home as possible. We’ll check your insulation, look at what ventilation you’ve already got (if any), and ask about any damp or condensation issues you’ve noticed, so what goes in is based on how your building actually behaves, not a guess.
Why Choose CoolStream?
We’ve been fitting heat recovery systems across Bristol and the South West for years now, for homeowners and businesses alike. It’s not just a case of screwing a unit to the wall. Getting it right means understanding where moisture builds up in a particular building, how air actually moves through it, and sizing a system that can keep up.
We stick around after the install too. If something needs a check-up, or a system isn’t performing quite how it should, you’re calling us directly. Not a call centre reading from a script.
Curious what this looks like in real properties? Take a look at our case studies and a few examples of how we’ve helped homes and businesses around Bristol sort out damp, draughts and high energy bills with heat recovery ventilation.
Frequently Asked Questions
What is a heat recovery system?
It’s a way of ventilating a building that doesn’t waste the heat you’ve already generated. Stale, moist air leaves the property, and as it does, its warmth gets transferred to the fresh air coming in to replace it.
What are the key benefits of a Heat Recovery System?
Fresher air, less condensation and damp, and lower heating bills. Because the air coming in is already warm, your heating isn’t having to work as hard, and you’re not relying on opening windows to get rid of stale air.
What are the types of Heat Recovery Systems?
There are two main options. Whole-house systems (usually called MVHR) run through ductwork and ventilate the entire property from one central unit. Single-room units just tackle one specific space such as a bathroom or kitchen, for example. Which one you need depends on the size of the property and where the problem actually is.
Are heat recovery systems suitable for homes?
Yes, and especially homes that are well insulated or airtight, where there’s not much natural ventilation left. We fit them a lot in newer builds and in houses that have had glazing or insulation work done, so you get the moisture control without losing the benefit of that extra insulation.
