Is it right for you?

Is this what your home needs?

A good fit if

  • Rooms that never get properly warm, or radiators that are slow to heat up
  • An old system at the end of its life, or a renovation that needs a new one
  • You'd like underfloor heating in some rooms and radiators in others

Probably not the right fit if

  • Only your boiler needs replacing and the rest of the system works well. See boilers
  • You're ready for a heat pump now. Start with heat pumps

We explain the available options and recommend solutions based on your home's requirements, rather than simply selling equipment.

Case studies

Before

HertfordshireExtended to 7 bedrooms and 8 bathrooms

The job
Two 25 kW boilers, 50 kW in total, and previous quotes suggesting another boiler to bring the capacity up to 65 kW. Our heat loss survey came to 24.5 kW.
The result
One 32 kW Vaillant ecoTEC plus, range rated down to 24.5 kW once the loft was insulated, with a 400 litre cylinder and underfloor heating in the extension. The client has since reported cost savings and the best hot water ever, despite having more bathrooms.
Read the case study

Hertfordshire6 bedrooms, 5 bathrooms

The job
A large property, and 5 heating zones, as the client requested.
The result
A Viessmann Vitodens 100-W system boiler with full weather compensation, and a 300 litre unvented cylinder giving priority hot water to all five bathrooms while maintaining efficiency.

Antony S.Google review · October 2026

Kirk Ferguson of NuRenewables Heating is the most knowledgeable heating engineer/plumber I have ever used and performed an absolutely superb job reworking how my entire heating and hot water system was configured for a large extension. This included installing a new boiler, powertank (to improve the water pressure), hot water cylinder, 3 bathrooms and a kitchen amongst other works.

Kirk is a delight to have in the house, is super tidy, but most of all is an expert in his field and applies a scientific approach to his installations to maximise the efficiency for the homeowner.

Shuaib Q.Google review · October 2026

Kirk and his team have been excellent in their assessment of our heating and plumbing issues. Professional friendly accessible and caring. Also responsive to any queries many months after the job. Our boiler was replaced and multiple plumbing issues. If you want first class service please contact Kirk!
