ASHPs we install

At Phoenix Plumbing & Heating, we supply and install all major types of air source heat pumps to suit a wide range of homes, properties and heating requirements across Maidstone and Kent. Not every system suits every property, which is why we take the time to recommend the best option for you. Here’s a breakdown of the main system types we work with:

01

Monobloc systems

Simple, compact and ideal for most UK homes

A monobloc heat pump contains all key components within a single outdoor unit. This makes installation quicker and more straightforward, with fewer internal parts and less disruption inside your home.

Benefits:

  • Ideal for smaller properties or where space indoors is limited
  • Lower installation cost compared to split systems
  • Less pipework and fewer components
  • Great for straightforward heating setups (e.g. radiators or underfloor heating)

We regularly install monobloc systems across Maidstone’s housing estates, bungalows and family homes.

02

Hybrid heat pump systems

The best of both worlds, especially in older or off-grid homes

Hybrid heat pump systems combine an air source heat pump with an existing gas or LPG boiler. The system switches automatically between the heat pump and boiler depending on demand, weather conditions and energy prices.

Benefits:

  • Perfect for homes with high heating or hot water demand
  • Keeps running costs low by using the most efficient heat source
  • Reduces strain on older heating systems
  • Ideal for gradual upgrades to low-carbon heating

We recommend hybrid systems for period properties or rural homes where completely replacing the boiler isn’t practical yet.

03

Split air source heat pumps

Flexible and powerful for more complex heating needs

Split systems consist of an outdoor unit and an indoor unit connected by refrigerant pipework. These are ideal for properties with higher heating demand or where the system needs to be integrated more deeply into existing heating infrastructure.

Benefits:

  • Better performance in colder weather
  • More installation flexibility
  • Quieter indoor operation
  • Often more energy efficient than monobloc units

Split systems are often a great fit for larger homes in areas like Bearsted or Aylesford, where performance and adaptability are a priority.

Air source heat pumps for commercial properties

Air source heat pumps (ASHPs) are becoming a popular choice for commercial buildings looking to help cut running costs, reduce carbon emissions and futureproof their heating systems. At Phoenix Plumbing & Heating, we design and install commercial ASHP systems across Kent and the South East, tailored to the unique demands of your property. Benefits of air source heat pumps in commercial settings:

01

Can lower long-term heating costs

02

Reduced reliance on gas or oil

03

Fewer carbon emissions to support ESG and net zero goals

04

Integration with existing radiators, cylinders, or underfloor heating

05

Suitable for zoned or large-scale heating systems

06

Access to funding through the Boiler Upgrade Scheme (BUS) or commercial incentives

We work with property developers, business owners, landlords and estate managers to deliver future-ready heating systems that offer performance, efficiency and compliance. All installations are carried out by our qualified Gas Safe engineers, and we’re happy to offer free advice on which boiler type best suits your needs.

What people say

“I recently used Phoenix Plumbing for a bathroom tap installation and was really impressed with the service. Later on, we had a plumbing emergency with a mains water leak, so I called Luke and he quickly arranged for one of his team to attend. The response was fast, professional, and the issue was sorted efficiently. Great service, great price, and excellent communication throughout. I would highly recommend Phoenix Plumbing to anyone looking for reliable plumbers.”
S Steve B.Google review · May 2026
“We were having issues with our boiler and Phoenix Plumbing and Heating were fantastic. They came out and resolved the issue quickly and were really professional. The engineer that came out was polite and knowledgeable, certainly an asset to the company. The lady I spoke to in the office ensured someone was out ASAP. Couldn’t have been happier and we wouldn’t go anywhere else now for any plumbing and heating needs. Highly recommended.”
L Lee F.Google review · May 2025
“We use Luke and his team annually to service our boiler. They always reply promptly and and are always clean and tidy when they leave. We have also used them a couple of times with other plumbing issues and again they're always very helpful. Thank you Phoenix 😀 would always recommend you !”

Straight answers

Frequently asked questions

Can't see your question? Call the office on 01622 585169 and speak to a real person.

Is your heating service work guaranteed?

Yes. All our plumbing and heating work comes with a one-year workmanship guarantee. All renewable systems, including air source heat pumps, come with a 2-year workmanship warranty, in line with the RECC mandatory standard. If anything goes wrong with our work within that time, we will come back and put it right.

Are your heating engineers on the Gas Safe register?

Yes, all our heating engineers are fully Gas Safe Registered, giving you peace of mind that your heating system is in safe hands.

How much is a heat pump?

The cost of a heat pump installation can vary depending on factors such as the size and type of heat pump, the complexity of the installation, and any additional components required. We offer free, no-obligation quotes for all our heat pump installation services.

Are air source heat pumps noisy?

Modern air source heat pumps are designed to operate quietly, with noise levels comparable to that of a refrigerator. Proper installation and maintenance can help minimise any potential noise issues.

How efficient are heat pumps?

Heat pumps are highly efficient heating systems, typically offering a coefficient of performance (COP) of between 3 and 4. This means that for every unit of electricity used to power the heat pump, you can expect to receive three to four units of heat output.
