If you’re thinking about upgrading your heating system, you’ve probably come across two main options: air to air and air to water heat pumps. Both systems use heat pump technology to provide efficient, cost-effective heating – but they work in different ways.
At WarmVent, we specialise in the best air to air heat pump installation in the UK, and we know that choosing the right system can make all the difference to your home’s comfort, running costs, and energy efficiency. In this guide, we’ll break down the key differences, benefits, and which system might suit your home best.
What’s the Difference Between Air to Air and Air to Water Heat Pumps?
Both air to air and air to water heat pumps extract heat from the outdoor air and use it to warm your home. However, they distribute this heat in different ways:
- Air to Air Heat Pumps: These work like a high-tech air conditioning unit in reverse. They take heat from outside and pump warm air into your home. In summer, they switch modes to provide cooling, making them a versatile all-year-round solution.
- Air to Water Heat Pumps: Instead of pumping warm air directly into your home, they transfer heat into water, which then circulates through radiators, underfloor heating, or hot water tanks.
While both systems are energy-efficient alternatives to traditional gas or electric heating, they serve different purposes. So, which one should you go for?
Why Choose an Air to Air Heat Pump?
If you’re looking for the best air to air heat pump, you probably want a heating system that’s both cost-effective and versatile. Here’s why air to air systems are the smart choice:
1. Superior Heating in Winter
Let’s be honest – UK winters can be brutal. An air to air heat pump is basically a super-powered heater, working efficiently even in cold temperatures. These systems are designed to extract heat from the air outside (even when it’s freezing) and bring it indoors, creating a warm and cosy environment without the high energy costs of traditional heating.
2. Cooling in Summer
One of the biggest advantages of air to air heat pumps is that they double up as an air conditioner. When summer hits and your home starts feeling stuffy, you can switch your heat pump to cooling mode, enjoying fresh, cool air at the touch of a button. Air to water systems, on the other hand, don’t provide cooling – so if you want year-round comfort, an air to air heat pump is the way to go.
3. Faster, Direct Heating
Air to air heat pumps work instantly. Unlike air to water systems, which rely on heating up water before distributing warmth, air to air systems blow heated air straight into your rooms. This means no waiting around for radiators to warm up – just instant, comfortable heat when you need it.
4. Energy Efficiency & Cost Savings
One of the biggest reasons homeowners switch to heat pumps is to cut their energy bills. Air to air heat pumps have a high coefficient of performance (COP), meaning they generate much more heat energy than the electricity they consume. This can lead to significant savings compared to electric heaters or old gas boilers.
Plus, because they don’t require additional water tanks, pumps, or pipework, installation costs are often lower than air to water systems.
5. Low Maintenance & Long Lifespan
Air to air heat pumps are designed to be low maintenance, with no need for extensive plumbing or water connections. With regular servicing, they can last 15–20 years, providing excellent long-term value.
When Would an Air to Water Heat Pump Be the Better Choice?
While we believe air to air systems are the best solution for most homes, there are certain cases where an air to water heat pump may be a better fit:
- If you have existing underfloor heating or large radiators, air to water heat pumps can integrate well with your current system.
- If you need a system to provide hot water, air to water systems can heat your water supply, whereas air to air systems do not.
- If you’re carrying out a full home renovation, it may make sense to install an air to water heat pump if you’re also upgrading your hot water and heating system.
That being said, if your priority is efficient heating, cooling, and year-round comfort without the need for water heating, an air to air heat pump remains the best choice.
To summarise, the best heating system depends on your home, budget, and personal needs. For most homes looking for the best air to air heat pump, an air to air system offers the perfect balance of comfort, efficiency, and affordability.
