Worcester Bosch Air Source Heat Pump Review

How Much Does a Worcester Heat Pump Cost?

A 5kW Worcester Bosch air source heat pump is likely to cost around £4,000 including VAT, but exclusive of installation. 

The overall cost including installation for a Worcester heat pump is likely to be £10,000+. However, thanks to the government's Boiler Upgrade Scheme, you'll have access to up to £7,500 in funding. 

Put simply, expect the net cost of your Worcester heat pump installation to be just over £4,000 for a 5kW unit. Naturally, the bigger the heat pump is (in kW), the higher the overall installation cost. 

Alongside this, the complexity of the installation has a huge bearing on price. For instance, if new pipework or radiators need to be installed (heat pumps work best with large radiators), costs will start to spiral upwards quickly.

What Size Worcester Heat Pump Do You Need?

A small 2-3 bedroom house is likely to need a 4kW-7kW Worcester heat pump. 

However, what size heat pump you need is based on:

• Property size (overall square footage)
• How many taps and showers it has
• Overall heating and hot water demand
• Quality of your property's insulation

The easiest way to determine exactly what size Worcester heat pump you need is to use our clickable heat pump tool here. Based on the information you give us, we'll be able to determine the exact model and brand of heat pump that's going to work the best with your property.

Worcester Air Source Heat Pump Range

The Worcester Bosch air to water heat pump range features 4 different models, with outputs from 4kW-30kW.

Below, we’ll outline some basic specs for the Worcester heat pump range. 

If you’re not sure what the most suitable brand, size and model of air source heat pump for your property is, use our clickable tool here. That’s going to suggest the best and most cost effective air source heat pump for your property.

Compress 5800i AW

The Compress 5800i AW is the quietest heat pump that Worcester Bosch offers. At a distance of 1m, it will only emit 32 dBa. That's a huge drop in noise compared to that of 50 dBa that the average air source heat pump emits. 

Available in 4kW, 5kW and 7kW outputs, the 5800i AW is suited to smaller installations, typically 1-3 bedroom houses.

You'll be able to get the 5800i AW heat pump as an outdoor or indoor unit. The indoor is much smaller. Dimensions sit at 700mm x 400mm x 290mm compared to the outdoor unit that's 800mm x 1100mm x 540mm. 

It's easily coupled with a 210L /  250L cylinder, or a slimline 180L cylinder for those that are short on space. 

COP (Coefficient of Performance) rating sits at 3.59 (359% efficient) and you'll be able to remotely access and control your heating via the HomeCom Easy app. 

This is slightly less economical than the most efficient heat pumps on the market (the Ideal Logic operates at 3.96), but still extremely impressive. 

Compress 2000 AWF

Next, we have the Compress 2000 (CS2000). If you're looking for a combination of space saving and an air source heat pump on the budget, this could be the heat pump for you. 

Available outputs include: 4kW, 6kW, 8kW, 10kW, 12kW, 14kW, 16kW, 18kW, 22kW, 26kW and 30kW. Put simply, you’ll find a CS2000 heat pump to suit basically every residential property from 1-6 bedrooms, as well as small commercial units. 

Sound levels at a distance of 1m sit at around 44 dBa. In comparison, the 5800i AW mentioned above is just 32 dBa. So, if you’re looking for a heat pump that emits as little sound as possible, the 5800i AW would be the go-to option. 

With the CS2000 AWF, you'll get:

• A high spec outdoor unit that doesn't require planning permission (4kW-16kW only, you'll need planning permission for the 18kW-30kW units)
• A monobloc setup which means low labour costs for installation
• Easy to use heating controls

Compress 3400i AWS

Another option from Worcester Bosch, is the Compress 3400i AWS; available as both an outdoor unit, and a wall-hung indoor unit. 

Output wise, there are limited options: 4kW, 6kW, 8kW and 10kW. However, these outputs would generally cover most properties in the 1-4 bedroom range. 

The wall-hung indoor unit is the smallest in the 3400i range, with its dimensions being 700mm x 485mm x 398mm; perfect for compact installations. 

For outdoor units, the 4kW is the smallest; 609mm x 976mm x 380mm. This is only suited to small properties (such as a 1-bedroom house), so if you need the 6kW-10kW unit, you'd need an outdoor space that's suitable to fit a 864mm x 975mm x 380mm air source heat pump. 

If we take a look at the specs of the 4kW, you'll get A+++ efficiency when operating at 35°C and A++ at 55°C. However, the sound levels of the 3400i are one of the highest in the Worcester Bosch heat pump range; 53 dBa. 

Compress 7001i AW

Finally, Worcester Bosch offers the 7001i AW Compress air to water heat pump. Typically, this is best suited to new-build homes, or those with excellent insulation. 

There are a range of outputs on offer: 5kW, 7kW, 9kW, 13kW and 17kW. That's going to mean if you have anything from a 1-5 bedroom house with 1-2 showers, this Worcester heat pump is going to be suitable. 

The standard warranty for the 7001i AW sits at 2-years, which definitely isn't enough when investing this kind of money in your heating system. However, if you use a Worcester and MCS accredited installer, your warranty will be extended to 7-years. 

Whilst this isn't the quietest heat pump that Worcester Bosch offers, at 39 dBa, the noise it emits is hardly going to be noticeable.

Energy Bill Savings Using A Worcester Heat Pump

The majority of people looking to upgrade to an air source heat pump from a gas boiler want to save money. 

The question is, how much money are you likely to save on your energy bills by using a Worcester heat pump?

If we take the Worcester Compress 5800i AW specs for our example, we'll see it works at a COP rating of 3.59. For every 1kWh of electricity it uses, it's going to produce 3.59 kWh of heat; it's 359% efficient. 

This is a massive improvement on a gas boiler. Even if you have a brand new A-rated gas boiler, it's unlikely its efficiency is anything above 0.94 kWh COP, or, 94% efficient. 

In fact, some older boilers operate at as low as 70% efficiency, so the Worcester 5800i AW would be 5.13x more efficient!

According to the Energy Saving Trust, you should expect to save over £600 per year if you’re using a G-rated boiler, making a Worcester heat pump an excellent investment!
