It is a bit of a minefield out there trying to research the different boilers that are available to you. Do you opt for a local plumber who may have a cheaper product but fails on the aftercare service and higher repair bills when your in need of some assistance. Or do you opt for the larger corporate boiler company and end up paying far more for than you really need to.

What are the best new boilers to buy in 2016?

There are many boiler manufacturers out there in the UK that proclaim that their boilers are top of the reliability list for 2016. So how do you find which boiler is the right fit for you if you are in the market for a new one?

Well, we don’t really have a top ten or a definitive ‘best boiler list’ for you as such because all the gas or combi or system boilers that we sell by Vaillant, Worcester Bosch or Ideal are in their own right the very best for you. Especially when you combine it with our unique monthly care² and maintenance plan.

What to look out for

When purchasing a new boiler – you should ask yourself the following questions to ensure you receive a good deal:

  • How reliable is that model going to be over the next 15 years?
  • What is the efficiency rating of that particular boiler
  • Can I add digital thermostat controls like Nest?
  • Will this new boiler be quieter than my existing or old boiler?
  • Is this new boiler going to slot into where my existing boiler is?
  • What will the installation cost be for a new boiler?

So how does a boiler actually work?

A modern boiler is a sophisticated machine, needing several internal components to function safely, such as a Pressure Release Valve (PRV) which regulates water pressure, an expansion vessel to accommodate increased pressure due to the water heating process and a fan to discharge waste gases caused by the heating process through a flue.

In addition, a number of devices external to your boiler can also be very useful, such as a main thermostat that monitors room temperature to switch your boiler on and off as the room falls and rises in temperature. You can also use a time switch to turn your boiler on and off (depending on room temperature) at certain times of the day, such as when you wake up or get home from work.

If you fit Thermostatic Radiator Valves (TRVs) to your radiators, you can even control the temperature of an individual radiator in a particular room so that it is hotter or colder than the rest of the house.

What type of boiler would you need for your home and why?

Vaillant Heat Only Or Open Vent Boiler Range

The Heat-Only or Open-Vent Boiler

The heat-only or open-vent boiler is also known as a condensing ‘conventional’ boiler or ‘boiler. It works by carrying the hot water to the central heating system, hot water cylinder and radiators. Conventional boilers are operated with programmable controls.

Pros:
  • Multiple hot water taps can be run at the same time. There is no loss of pressure for multiple hot water users.
  • Requires extra room for both a hot water cylinder and cold water tank.
  • Can also install an electrical immersion heater next to the hot water cylinder as a back-up.
  • Good choice for a larger home that has more than one bathroom.
Cons:
  • Generally larger so takes up extra space.
  • Once the hot water is used up you will have to wait for the tank to refill (or use an additional immersion heater). The size of the cylinder you choose will depend on how much hot water you expect to use.
  • Requires programmable controls to switch your heating and hot water on / off at certain times of the day.

 

aillant Combi Boiler Range & Prices

The Combi Boiler

The combination or ‘combi’ boiler takes its name from its dual function: it’s a high-efficiency water heater and a central heating boiler combined in one compact unit. A combi boiler provides heating and hot water directly from the boiler, which means almost immediate hot water.

Pros:
  • On-demand limitless heating and hot water provided directly from the boiler
  • Does not require a hot water cylinder or cold water tank.
  • Generally smaller so takes up less space.
  • Has fewer elements and is faster to install.
  • Does not require programmable controls to switch your heating and hot water on / off at certain times of the day.
  • A good choice for a smaller home with only one bathroom.
Cons:
  • In larger households (with more than one or two bathrooms) there is always the risk of loss of water pressure if more than one person is running the hot tap at a time.

Our Vaillant System Boiler Range

The System Boiler

The system boiler is very similar to a heat-only or conventional boiler. It directly heats your central heating system, producing hot water stored in the hot water cylinder – which in turn is usually tucked away inside an airing cupboard. Like a combi boiler, it’s little more compact than a conventional boiler, thanks to its mainly pre-built components.

Pros:
  • Multiple hot water taps can be run at the same time. There is no loss of pressure for multiple hot water users.
  • Easier to install because many components are pre-built in, removing the need for an expansion tank or supply feed.
  • Can also install an electrical immersion heater next to the hot water cylinder as a back-up.
  • Does not require a cold water tank if you have a pressurised mains-supplied hot water cylinder, freeing up a little extra space in the loft.
Cons:
  • Generally larger so takes up extra space.
  • Requires programmable controls to switch your heating and hot water on / off at certain times of the day.
