Greenline air source heat pumps
Thinking of switching to a heat pump? Good choice - you can benefit from our many years of experience designing, supplying, and supporting renewable heating systems across the UK.
Our approach
Heat pumps are actually fairly simple - they tend to just reliably work. It is the design of the heating system they connect to, how it is all commissioned, and controlled that is really vital. This is why our focus is on good system design and control, and our aim is for you to end up with reasonable running costs, reliable hot water, consistent room temperatures, and a cosy home. Our designs are usually as "simple as possible, but not simpler" - this can mean that we do not specify items like buffer tanks or secondary pumps which others might. Fewer parts means lower material and labour costs.
Your options
Option 1: Free System Overview - One of our specialists will talk with you to find out a little more about your situation and what might be right for you (and perhaps more importantly, what might not be right). Assuming that a heat pump seems a good fit you can then make two choices - a rough whole-house heat load estimate will allow us to sketch out a suitable system for you, and then when you wan to take things further we can introduce you to the local installer who will take things from there. This option is free of charge - we would eventually be supplying the unit and parts to the installer assuming the project goes ahead. We remain on hand as a helpful contact for both you and the installer before, during, and after installation.
Option 2: Detailed Design - Or for a small charge we will go into more depth, starting with detailed room-by-room heat load calculations that then allow us to do more detailed heating system design and specification. This assumes that you have plans and details available for your house - if not then we recommend that you choose option 1, and that the installer does these calculations from scratch.
The installer that we eventually introduce you to is given access to our calculations and they then tweak them following their site visit. This puts everything one step ahead, and means we can work in more depth together with the installer on the system design.
We do not ask you to sign up to anything - only once you have been in touch with the installer, they have been for a site visit, and then presented you with a quote is there a decision for you to make - and that would be between you and the installer.
Why Greenline?
We supply Greenline heat pumps, and some of the reasons why we have chosen them are;
- They are quiet and discrete - with a dark casing that blends neatly into most gardens.
- Long-lasting - they have a really durable outer casing made from recycled material
- Easy installation - means less hours charged by your installer
- Efficient and Flexible - work across a wide temperature range, and can deliver low running costs
- MCS certified - eligible for the BUS government grant scheme
- Smart connected - monitor performance and get remote support
Next Steps
Switching to a heat pump is a big investment - take your time over it to get it right. There are some very good books available and we recommend that you read one of them first to inform, empower, and help you to avoid pitfalls. You can order copies of Bodgebuster direct from us via the link below, or there is also the more recent "Ultimate Guide to Heat Pumps" available direct from the Renewable Heating Hub, and which one of our founders contributed three chapters to.
So do get in touch with us and we can help you get a home that feels consistently warm, has reasonable running costs, and gives you peace of mind knowing it's low-carbon and made to last.
