Engineering the Transition from High to Low Flow Temperatures

Traditional combi and system boilers scorch water to 70°C in short bursts. Heat pumps operate far more efficiently by maintaining a steady 40°C–50°C flow temperature, warming your home evenly 24/7.

Frequently Asked Questions

Everything you need to know about engineering standards, grants, and living with renewable systems in Kent.

help Can I replace my old oil boiler and oil tank?

Yes! Replacing an oil boiler yields the greatest financial and environmental savings. We also safely siphon remaining oil and arrange licensed tank removal.

help Will a heat pump cost more to run than a gas boiler?

With gas prices fluctuating and heat pumps operating at 350%+ SCOP, running costs are comparable or lower — especially when paired with smart off-peak electricity tariffs like Octopus Agile or Cosy.

help What happens to my old boiler?

Our engineers decommission the gas or oil supply safely, remove the boiler unit, and take all scrap metal and debris to licensed Kent recycling facilities.

help Do I need to upgrade my electrical consumer unit?

During our survey, we inspect your fuse box and main incoming fuse. If an electrical upgrade or isolator is needed, our certified electricians manage it as part of the job.
