Fitting heat pumps to hot water cylinders

Today's plumbing and heating industry has definitely started to move towards renewables and energy efficiency with the release of many energy efficient products for homes and businesses.

A now common product to have fitted is a heat pump and its important to understand how this fits in with the rest of a heating system.
 

Hot water cylinder

The average flow temperature for a medium temperature heat pump is around 50oc,the problem with this is that your average cylinder is set up to work with around 60oc.If the wrong type of cylinder is fitted with a heat pump then the heat pump will suffer with some issues such as short cycling and poor hot water delivery.

 Their are two types of hot water cylinders that are compatible with heat pumps,these are the open vented thermal store type and the stainless steel invented cylinder type,both these cylinders are perfect for use with a heat pump.

A open vented thermal store is a cylinder that has been specifically designed for use with a heat pump that will provide the mains pressure for a households hot water.the difference between this type of cylinder and a normal one is that the stored water is constantly hot where as the cold water runs through a heat exchanger which is inside the cylinder

Because the hot water is produced instantly from the cold water supply the water quality will be the same as normal so this means a installer can fit a thermal store cylinder with a heat pump and not need to raise the temperature to prevent bacterial growth.

Thermal stores do not need a pressure or temperature relief valve, which means there is no need to incorporate discharge facilities in the system to keep in check with Part G of the Building Regulations, which covers discharge into soil stacks.

So that was a brief over look at fitting heat pumps to hot water cylinders. All ways check that the cylinder your buying is compatible with heat pumps if its your intention to fit one.I hope today's post was helpful and interesting thanks for reading.

How does insulation work

 Insulation is used to keep the heat inside of your home for as long as possible,as well as keeping your bills down.

Insulation is available in a few different material types.
 .fibreglass
.foam
.cellulose

Insulation can be used in lots of places through out a home but is most commonly used for walls and lofts as these are the most common areas of heat lose.

Insulation is designed to stop heat from passing through it by creating a resistance so that hot air cant pass through it easily trapping the hot air inside your home for longer.

Insulation resistance is normally measured in 'R'.The higher the R value the more resistance the insulation has.You can pick up insulation in rolls or in a Bat.Insulation that comes in these forms is best suited for use between the joists and ceilings well as walls.


Blown in insulation is a type of insulation that is applied using a spray.This type of insulation is best suited for homes that have been completed but are missing insulation.This type of insulation can be difficult to use as it needs to be blown through a gap.If a gap cant be found then a hole has to be cut to apply the spray.This type of insulation is also very good for use between walls that are a unusual shape or for hard to reach places.

 Rigid insulation comes in a few variations of extruded and expanded polystyrene foam, polyurethane foam and polyisocyanurate foam boards.Most of these types of insulation come with a protective foil to keep water from being absorbed by the insulationt,this type of insulation is very efficient considering how thin it is. Rigid insulation's although excellent does require certain fire safety measures though.

How does a combi boiler work.

In todays post I will be covering the basics of combination boilers,

So lets get started.                                                

Combi boilers or combination boilers are the most common type of boiler you will find in a home. Around 65% of the UK's homes have a combi boiler fitted.                  

Combi boilers are popular because they don't need a separate water tank to work so you'll have more room in your loft,as well as this combi boilers can be hidden away easily due to their size.

The size of these boilers means their best suited to small house holds with one bathroom and come in common power outputs ranging from 24kw to around 30kw.A combi boiler has the benefits of being able to provide instant hot water as well which is another reason their becoming so popular around the UK.

Below is a simple diagram showing a combi boiler setup

Their are however some disadvantages to the combi boiler heating system.

A combi boiler will only really be able manage one shower or bath at a time.

As I mentioned earlier ,a combi boiler is better suited for a smaller house hold with only the one bathroom to manage.If you've got a combi boiler and 4 bathrooms your going to experience some issues.

The combi boilers hot water flow rate will be lower than some other boiler.

This is considered to be a small price to pay when you think about the space a combi boiler saves,the fact that you don't need a roof tank, and you get instant hot water.

Well that's the basics of a combi boiler system.I hope this post was interesting and helpful, feel free to leave a comment.
