When To Invest In A New Boiler

oil-boilerA shiny new boiler including installation can cost as little as £2000.00, though this is dependent on many factors. They include upgrades that might be needed for the heating system, the quality of boiler installed, the positioning and of course the tradesman.

If your boiler is over 30 years old the likelihood is that it is due for replacement, parts may be difficult and expensive to source and the efficiency won’t be that great.

If you are intending to have an extension, new kitchen e.t.c. then you might want to consider whether your boiler is in the right place for you and where the positioning of a future boiler may have to be. Your current boiler positioning may not be suitable for a new boiler due to flue and fire-valve considerations for example.

If your boiler is breaking down regularly, again, it might be wise to put those call out costs towards a new efficient, reliable boiler.

What is a condensing boiler?

condensing-boilerAs of the 1st of April 2005 building regulations state that any new or replacement Oil boiler needs to be a condensing boiler. Only in exceptional circumstances does this not apply.

A condensing oil boiler is a boiler that re-uses previously wasted heat from flue exhaust gases. They will have a bigger heat exchanger or an additional heat exchanger, which allows the water in the water jacket to extract more heat from the exhaust gases than non-condensing boilers.

As the water vapour cools it turns into water (condenses) and leaves the boiler via a condense pipe (and trap) to a suitable termination point.

Condense water is slightly acidic, between 3-5 PH and thus would ‘rot’ ‘old fashioned’ boilers heat exchangers. Condensing boilers are generally made of stainless steel to prevent this. Whilst not great, the slightly acidic nature of the water is no worse than a lot of fizzy drinks.

Know your Oil Boilers!

There are 3 types of Oil Boilers that can be installed and used as a source of hot water

  1. Combi Boiler (or combination boiler).
  2. Regular Boiler (or traditional/conventional boiler).
  3. System Boiler.

 

Combi boilers provide heating and hot water directly from your boiler whilst regular and system boilers heat your central directly and produce hot water for your domestic hot water cylinder.

Situations where an oil fired combi boiler are best suited include:

  • You live in a flat/bungalow with little or no roof space.
  • You want to convert your loft into an habitable room, requiring the removal of loft tanks.
  • You require hot water ‘on tap’.
  • You have a seperate annex for a family member.

 

Note: The siting of the combi boiler is very important as it loses efficiency when there are long draw offs (pipe runs to taps, showers e.t.c.).

Situations where an oil fired system/traditional boiler are best suited include:

  • You require a system that allows the use of several draw offs (taps, baths, showers e.t.c.) at once.
  • You have low cold mains pressure coming into the property.
  • Your property has bathrooms, kitchens e.t.c. a long distance from each other and/or boiler siting.

 

Before selecting a boiler for installation, it is important to discuss your needs with your OFTEC registered oil engineer. Contact us now and let us help you get the right boiler.

Spring – The Perfect Time For a Boiler Service

oil-boiler-serviceAs summer approaches and the bitter cold nights of the winter disappear from our mind so do our thought move from our heating to the sunny delights of Bermuda shorts and ice lollies. Spring and summer is the ideal time to have your boiler serviced and/or have work carried out on your heating system. The benefits of having heating work carried out in these months include:

1 -The greater availability of your OFTEC registered engineer (winter months tend to see us busy with breakdowns and emergency boiler replacements).

2- A service can identify potential remedial work and system upgrades which can then be carried out when the need to have the heating turned off won’t affect the household to the degree that it would do during the winter.

3- External Oil boilers should ideally be worked on in the dry as water and electrics don’t mix. Many winter services are called off due to unsuitable weather conditions, i.e. rain leading to a new appointment having to be scheduled.

4- Many engineers increase their prices during the winter months. (NOT US!)
