Grant Vortex Boiler House 15-21kW heat only Oil boiler frequently asked questions

Is the Grant Vortex Boiler House 15-21kW a system boiler, a combi boiler or a regular boiler?

The Grant Vortex Boiler House 15-21kW is a oil heat only boiler.

You may hear a heat only boiler being called a regular boiler, a conventional boiler or a standard boiler. With a regular boiler, you need to find room within your property for a hot water cylinder with an immersion heater (usually in a landing cupboard or airing cupboard) and a cold-water tank (usually in the loft). The immersion cylinder is what keeps your hot water warm all day.

With a regular boiler, you schedule your hot water and heating for set times during the day or week, but if you forget to do so and the hot water runs out, you'll need to wait for your boiler to heat enough water before you can have a bath or shower - that can sometimes take up to an hour.

A regular boiler is suitable for homes with more than one bathroom or larger families when there is high demand for hot water. Although combi boilers are the most popular type of boiler in Britain, water pressure, volume and temperature drop if there is simultaneous demand from two or more points - for example, someone running a hot water tap when someone else is in the shower.

Should I install a Grant Vortex Boiler House 15-21kW heat only boiler in my home?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big the boiler is - it means how big its "output" is.

This Grant Vortex Boiler House 15-21kW heat only boiler gets its power from oil and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher oil bills.

The Grant Vortex Boiler House 15-21kW heat only boiler has an output level of 21 kW, so which types of property would it be appropriate for?

Most experienced heating engineers would suggest that the most suitable type of property for installing a Grant Vortex Boiler House 15-21kW heat only boiler in would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Grant Vortex Boiler House 15-21kW dimensions

The Grant Vortex Boiler House 15-21kW has the following dimensions - 714 mm high, 431 mm wide, and 597 mm deep.

If you want to replace your floor-standing boiler with a more compact, wall-mounted model, this will give you and your family more space. Hundreds of thousands of homes in the UK still use floor-standing boilers like the Grant Vortex Boiler House 15-21kW, but wall-mounted models have been the most popular choice for homeowners over the last two decades. We can replace your floor-mounted unit with a wall-mounted unit, but please be aware that the cost of installation will be higher if we need to replace your current piping.

However, you can recoup this investment in full over a few years with the savings you make on your oil bills.

Vortex Boiler House 15-21kW – non-condensing or condensing?

We recommend the Grant Vortex Boiler House 15-21kW as it is a modern condensing oil boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more oil.

Condensing boilers significantly reduce your quarterly oil costs and they're better for the environment.

Is the Grant Vortex Boiler House 15-21kW heat only boiler good for the environment?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Do the figures suggest that installing the Grant Vortex Boiler House 15-21kW heat only at your property would help in the fight against climate change?

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Grant Vortex Boiler House 15-21kW was awarded an efficiency rating of 90.7% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The Energy Related Products Directive (ERP) was introduced in 2015 and applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Grant Vortex Boiler House 15-21kW has an ERP rating of "A".

How long am I covered by the warranty for if the Grant Vortex Boiler House 15-21kW breaks down?

Parts and labour charges incurred for repairs made to your new Grant Vortex Boiler House 15-21kW are covered by a 2 year warranty.

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your oil bills will go up and not down.
