The Johnson & Starley QuanTec Combi is available in a range of sizes to suit most homes.
Made in Great Britain, the Johnson & Starley QuanTec Combi is an efficient boiler that uses cutting-edge technology to reduce carbon emissions and fuel bills. It comes in three power outputs to satisfy the needs of small, medium and large homes and it’s one of the most reliable combi boilers on the market today. This boiler is also easy to install and maintain, which should help to save you money on fitting and maintenance costs.
How Much Does this Boiler Cost?
The QuanTec Combi from Johnson & Starley typically costs between £710 and £920, including VAT. As it’s available in 24kW, 28kW and 30kW outputs, the price will depend on which model is needed to meet your heating and hot water requirements. You also need to pay a Gas Safe registered engineer to fit the boiler and this can cost anything from £500 to £1,500. To compare prices and find the best deal on the boiler and installation, you should get a fixed-price quote from a range of local and national installers.
How will I know if this Boiler is Suitable for My Home?
Combi boilers work by taking water from the mains to warm up your radiators and deliver instant hot water to your taps. The good news is that they don’t require any additional components, such as tanks or a water storage cylinder, so the QuanTec Combi is a good choice if you don’t have much storage space at home. As combi boilers don’t cope well when two or more baths or showers are running at the same time, they are better suited to homes with one bathroom.
The 24kW and 28kW QuanTec Combi models are ideal for small to medium-sized homes with one bathroom and the 30KW model is suitable for larger homes with a bathroom and an ensuite. It’s important to pick the right size/output for your home, so be sure to get an engineer’s opinion before installing a new boiler.
Is it a High Efficiency Boiler?
Johnson & Starley’s flagship model, the QuanTec HR28C, features integral passive flue heat recovery technology to give energy savings of up to 25%. This model meets Boiler Plus requirements without any additional measures and is the most efficient boiler out there. It’s also A-rated for efficiency and can achieve A+ efficiencies when connected with the Honeywell Evohome smart thermostat.
Does this Boiler have a Good Range of Controls and Features?
Yes. The QuanTec Combi features a full condense stainless steel heat exchanger with in-built heat recovery, which results in increased efficiencies with running cost savings of around £100 per year over a non-heat recovery combi boiler. This boiler comes with horizontal and vertical flue options and all components can be accessed from the front of the boiler to make servicing and maintenance easy for your engineer. It also features frost protection and cool door burner technology.
How long is the Warranty on this Boiler?
The Johnson & Starley QuanTec Combi comes with an 8-year parts and labour warranty.
