Air Source Heat Pump Installation

  • 16kW LG Therma 32 ASHP installed with their radiator system
  • Efficiency savings over 7 years of an estimated £2464
  • RHI payment approx £11,346
  • MMSP payments of £1610
  • Total payments and savings of £15,420 over the next 7 years!
  • These guys are amazing. The team's interaction, their approach to the work ( including problem-solving) and the very strong work ethic that is evident - they are grafters. A pleasure to be around (polite and respectful).

    I would highly recommend them.

Air Source Heat Pump Installation

Pete was able to claim Home Energy Scotland’s grant of £7500 as well as use their interest-free green loan to install their Midea air source heat pump. The client also has solar PV and battery storage installed to maximise their energy efficiency. This, paired with a smart energy tariff from their supplier, is going to allow them to generate energy to use, and charge their batteries at a cheap rate to then use to power their heat pump.

Switching from fossil fuels to this technology is going to save them a lot of money which is vital as the energy crisis increases prices.

  • "Fantastic from start to finish. Very detailed discussion about upgrades to radiators etc required and they always had plenty of time to discuss various options. They were happy for us to take our time to discuss the various options and agree on the final plan. During the installation they were so neat and tidy - not a drop of radiator fluid anywhere despite changing almost every radiator in the house! Also knowledgeable about the Home Energy Scotland process for the loan and cashback."

Air Source Heat Pump Installation

  • "We have been very impressed with the standard of CMS surveyors’ service. They have been professional from start to finish with a high standard of workmanship and good attention to detail. Right from the initial assessment, we were fully informed of the process and options available and given time to consider these. They were even happy to accommodate changes as we went along. CMS were keen to work to our needs and happy to give advice without ever feeling rushed or pressured. The engineers who fitted the heat pump and new radiators worked extremely well as a team, arrived on time and left everything tidy and organized at the end of each day. Everyone from CMS has been extremely helpful and the whole experience has been really positive. We are happy to highly recommend this company. "

  • 5 year payback which equates to 20% annual return on investment.
  • Total savings over 20 years is upwards of £140,000!
  • This client opted to fund the install which was going to offset some of their corporation tax liability.
