Replacement Boilers

Prices are subject to survey plus V.A.T

Heating takes up roughly 60% of your annual energy bills. A new energy efficient A-Rated boiler would make a big differece to your overall annual energy spending.

Modern boilers are more efficient for many reasons, the main one being that they are all condensing boilers. All well-maintained boilers burn their fuel very efficiently, inevitably heat is lost in the hot gases that escape up the flue. A condensing boiler has a larger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient.

At NMU4 Contracting Ltd we sell, supply & fit new A-Rated energy efficient boilers at exceptional costs. We have 3 schemes available; Gold, Silver and Bronze each has different boiler av available at a different cost and with either a 2, 5 or 10 year guarantee that comes with the service.

Boiler Pricing

Your Boiler is a complex piece of machinery.

Consequently new boilers aren't cheap and prices vary greatly depending on the brand, size and type. Prices can be as much as £2,500, so it's important to get all the facts before you choose your replacement boiler.

The initial costs of boiler installation costs and boiler replacement costs are often offset greatly by the savings you make due to your new, more energy efficient boiler. This will have an impact on your annual energy costs.

Boiler Savings

What is the money saving timescale?

Bbuying a new boiler can lead to uncertainty. The key question many of us face when deciding whether a boiler upgrade is worthwhile is how long will it take to pay for itself.

Whe the decision is made to replace that old energy-inefficient boiler, you can expect to save some money on your gas bills. The boiler installation or boiler replacement costs are likely to be significantly outweighed by the savings you are in line to make. Based on a home with gas central heating with a 60% efficent boiler, you ccoould save up to £237 per year on yoour energy bills.

Boiler Upgrade.

When to get a new boiler.
  • Your boiler is beyond the point where it's cost-efficient to repair it.
  • Your boiler doesn't give you the control over your heating that you need.
  • If your system has a 'dry cycle'.
  • If your boiler has a continuous pilot light.
  • If your boiler is on the floor rather than on the wall.
  • If your boiler is G-rated for energy efficiency.
  • If you're selling your house, a new boiler could add to its value.
