If you’ve taken a walk around Farnham or Guildford lately, you might have noticed these neat little fan units sitting outside people's houses. They look a bit like air conditioning units, but they’re actually the secret weapon in Surrey’s fight against rising energy bills. We’re talking about Air Source Heat Pumps (ASHPs), and honestly, it’s about time they got the spotlight they deserve.
At Heat Eco Building Services, we’ve been busy installing these across the county, and the buzz is real. Whether you're in Bordon or over in Farnborough, people are looking for ways to future-proof there homes, and heat pumps are top of the list. It’s not just about being "green", though that’s a huge part of it, it’s about making your home more comfortable and way more efficient.
So, what is this "Magic" box anyway?
We get asked this all the time. "How can you get heat out of cold air?" It sounds like a bit of a trick, doesn't it? But it’s actually just clever physics. Think about how your fridge works; it takes heat from the inside and pushes it out. A heat pump just does that in reverse. It pulls heat from the outside air, even when it’s freezing cold outside, and pumps it into your home to warm your radiators or underfloor heating.
Who wants a nasty, inefficient bathroom in there house these days when you could have a cozy, eco-friendly setup instead? We’ve seen a massive shift in how our customers in Surrey think about their heating. They want something that’s built for the future.
(Note: I will generate a second, more specific technical isometric image here)
Wait, let me get a better technical illustration for you.
How it actually works (The simple version)
The unit outside has a refrigerant fluid inside it. This fluid has a very low boiling point. When the outside air passes over the heat exchanger, the fluid turns into a gas. We then compress that gas, which makes the temperature shoot up, kind of like how a bike pump gets hot when you’re using it. That heat is then transferred to your home’s water system.
It’s efficient. Like, really efficient. While a top-of-the-line combi boiler might be about 90% efficient, a heat pump can be over 300% efficient. That means for every 1kW of electricity you put in, you get 3kW of heat out. You can't argue with that logic, can you?
Why is Surrey leading the charge?
Surrey is a bit of a hotspot for this tech for a few reasons. First off, we have a lot of properties that are perfect for it. Whether it's a modern build in Guildford or a renovated period home in Farnham, our residents are generally pretty clued up on sustainability.
Also, let’s be honest, we care about our local environment. We’re lucky to live in a beautiful part of the world, and keeping our carbon footprint down helps keep it that way. By switching from a traditional gas or oil boiler to an air source heat pump, you’re significantly cutting your home’s emissions. It’s a win for you and a win for the Surrey hills.
We’ve worked on plenty of projects where we integrate these systems into commercial building maintenance as well. Businesses are starting to realise that being eco-conscious isn't just a trend; it's a smart financial move.
The Big Question: What about the cost?
This is usually where people pause. "Aren't they expensive to install?" Well, they used to be. But in 2026, the landscape has changed.
Right now, the government is practically throwing money at homeowners to make the switch. The Boiler Upgrade Scheme (BUS) currently offers a massive £7,500 grant toward the cost of an air source heat pump. That’s a huge chunk of change taken right off the top. Plus, there’s 0% VAT on the installation.
When you add that all up, the out-of-pocket cost for a heat pump can often be very close to what you'd pay for a high-end boiler installation. And once it’s in, your running costs can be significantly lower, especially if you’re moving away from old electric storage heaters or an expensive oil system.
We use fancy tools like this thermal scan above to see exactly where your home is losing heat. Before we even think about installing a pump, we make sure your home is ready for it. There’s no point putting a high-tech heating system into a house that’s as leaky as a sieve!
Living with a Heat Pump: What’s it really like?
It’s a different kind of heat. If you’re used to radiators that get "burning hot" to the touch and then go cold, a heat pump will be a change. They provide a steady, consistent warmth. It’s more of a background heat that keeps the whole house at a lovely, even temperature all day long.
It works incredibly well with underfloor heating. Imagine waking up in your Surrey home and stepping onto a warm floor while it's frosting outside. That’s the dream, right? We’ve installed some stunning modern living spaces that use this exact setup, and the comfort levels are off the charts.

Is your home a good candidate?
We’re always honest with our clients. While we love heat pumps, they aren't a "one size fits all" solution. They work best in homes that have decent insulation. If you’re living in a drafty old cottage with single-glazed windows, we might suggest doing some eco-friendly upgrades to your insulation first.
Here’s a quick checklist of what makes a great candidate:
- Insulation: Do you have loft and cavity wall insulation?
- Space: Do you have a bit of room outside for the fan unit?
- Heating System: Are you willing to potentially upgrade a few radiators to larger ones (to handle the lower flow temperatures)?
- Future Plans: Are you looking to stay in your home for a while and reap the long-term savings?
If you're nodding your head to those, then you're probably ready to join the Surrey heat pump revolution.
The Heat Eco Process: How we do it
When you call us in, we don’t just show up and start bolting things to your wall. We take a look at the whole picture. We’re experts in boiler options and heating, so we’ll tell you straight if a heat pump is the right move for you.
- The Survey: We’ll check your insulation, your current pipework, and where the unit can go.
- The Design: We calculate exactly what size pump you need. Too small and you'll be cold; too big and you're wasting energy.
- The Grant: We handle the paperwork for the £7,500 BUS grant for you. You don't need that headache!
- The Install: Our friendly team gets the job done with as little mess as possible. We pride ourselves on being reliable and fast.
- The Handover: We show you how to use your new system so you’re getting the most out of every penny.
Making the Switch
Look, the way we heat our homes is changing. Whether it's the push for net-zero or just the desire to stop giving so much money to energy companies, air source heat pumps are the future. If you're in Bordon, Farnham, or anywhere else in Surrey, now is the perfect time to look into it while the grants are so high.
We’re passionate about this stuff. There’s nothing we like more than seeing a client’s face when they realise they can have a warm, cozy home and a lower carbon footprint at the same time. It’s lovely, really.
If you’re thinking about it, give us a shout. We can talk through your options, look at your current bathroom or kitchen plumbing, and see how a heat pump could fit into your life. The results speak for themselves: and your wallet will probably thank you too!
Who knows, maybe next time we're walking through Guildford, it'll be your house with that neat little fan unit outside, quietly doing its thing and keeping you toasty.
Stay warm (and eco-friendly),
