Southampton Commercial Heat Pump Installations

Heat pumps are an alternative to central boilers and furnaces when it comes to heating. They transfer heat from hot areas to cold sections during the cold weather. Likewise, they move cold air from cool areas of the building to hot regions during the hot season. They are more efficient in terms of energy consumption than standard heating and cooling commercial equipment. Currently, the UK government offers incentives to companies that invest in renewable sources of energy that includes the use of heat pumps.

No1PHD offers quality installation, service and repair of heat pumps of various brands and sizes across Southampton. We have teams of qualified heating technicians who make size estimates, brand recommendations, installations and offer full manufacturer warranties.

Make Huge Savings

One of the major benefits of choosing a heat pump is the energy savings that your business stands to make. While the equipment uses electricity to pump the heat or cold air in places that it is required, it does not need to generate the heat or cool the air. These two processes are energy-intensive and make a large portion of the heating equipment operating costs. When you hire our team for Southampton heat pump installations, you recover the cost with energy savings over the lifetime of the equipment.


Reduce Carbon Footprints

With our heat pumps, your business will lower the amount of C02 that you generate in the atmosphere. Not only is this beneficial to the environment, but a low carbon footprint is also one of the key areas checked when looking for certifications such as the ISO 14001. Besides, the business can market itself as an environmentally conscious organisation.

Ideal for Companies Eligible for ESOS

If your company is eligible for the Energy Savings Opportunity Scheme, which is a mandatory energy management scheme that is run by the Environment Agency, our Southampton heat pump installation technicians can help you meet its recommendations and requirements. At the same time, your business will also get other benefits, such as a low carbon footprint and energy bills.



With the use of heat pumps, the heat transfer process do not include combustion. Therefore, you expect the pump to last longer than your traditional boiler and, at the same time, require minimal maintenance. On average, most ground source heat pumps last 30 to 40 years while air source pumps last 20- 30 years. This is more than twice the expected lifetime of a conventional commercial boiler.

Then, we will make a quote covering the equipment and installation works. When you give us the green light to start the work, we shall avail of all the tools and equipment on site to ensure that we are done as soon as possible to prevent extended downtimes. You can also hire our Southampton heat pump installation teams to change your conventional heating equipment to a heat pump.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
