Important Tips

 

We recommend with every boiler purchased having some kind of extra Scale Inhibitor system in place.

This will increase the longevity of the boiler.

Our best sellers are listed above, you can select one of these with your boiler purchase.

Listed below are the differences and fitting instructions to help you with your choice, also at the bottom of the page is a short explanation what hard water is and what it causes.

This Boiler is a straight swap for a Potterton Performa Combi Standard Efficiency non condensing boiler and the Baxi 105 / 105E Combi Standard Efficiency non condensing boiler

Horizontal Flue Kit & Time Clock is included In price

Technical Data

• 30.5KW maximum Heating output
• 11.9KW minimum Heating output 

Important Characteristics

 

• Ideal for the larger home and supplying that extra Domestic Hot Water requirement.
• So easy to install and maintain
• No tank or cylinder
• Minimal pipe work
• Substantial savings on materials
• Quick & easy installation
• Easy access to all main components
• Servicing time and bills greatly reduced
• Conversion Kits available for liquid petroleum gas users Pipe work to the boiler can be completed prior to the boiler installation with the aid of a pre pipe fixing jig.

Simple controls save you even more

 

Ten LED status indicators ensure simple control and diagnostic functions, a modulating output maximises economy to save your heating bills. It has an independant control of domestic hot water and heating temperature.An optional integral central heating timer kit is available. 

 

Service and Support

 

Baxi Potterton aims to provide quality Technical Service and Support. In the unlikely event that a service visit is required, our nation-wide network of Service Agents will endeavour to attend within 48hrs (normal working days) or at a mutually agreed time.

Please note: that all boilers need to be fitted by registered CORGI fitters and will have to be approved by them.  Please do not purchase any items without consulting your plumber before.

Please do not arrange for a plumber until you are in receipt of your goods and are completely satisfied.

But, it has to be mentioned, that the flow can be limited if other taps are running simultaneously. That said, it provides almost instantaneous steaming hot water. Literally on tap. Whenever you need it. And no waste. There is no storage cylinder to heat first. Or to run cold. There are no tanks to find space for.

Pro's

• Almost instantaneous hot water
• Drinkable water at all taps
• No tank in the roof space
• No cylinder so more space
• No airing cupboard so more space

Glossary of Technical Terms

Combi

This is the name given to a boiler that heats water instantaneously on opening a hot tap. There are no tanks in the loft and no storage cylinder. The water is fed from the mains so the water pressure is generally stronger.

 

Controls

All boilers have controls that allow you to adjust the water temperature (thermostat). You may also find a water pressure gauge and a digital or mechanical timer.

 

DHW

Domestic Hot Water.

 

Expansion Vessel

As the water in the heating system gets hot it expands; in sealed systems the 'expansion vessel' (a small pressurised container) accommodates the extra volume.

 

Flow Rates

Generally the term 'flow rates' is associated with combis. It refers to how much water (usually measured in litres) can be heated as it flows through the pipes in a given time (usually per minute). A powerful boiler will heat more water therefore providing a better flow rate.

 

Flue

All boilers have some sort of flue system; there are typically two types as follows:

Concentric

This system comprises of two pipes one inside the other, the internal pipe takes the exhaust gases from the boiler to the atmosphere and the outer pipe supplies air to the boiler. The majority of concentric flues are a maximum of 4 metres in length and have a wide range of flue bends and extensions. This provides greater flexibility in positioning your boiler.

 

Twin Pipe

This system comprises of two pipes, the first pipe takes the exhaust gases from the boiler to the atmosphere and the second pipe supplies air to the boiler. This flue system is useful when the pipes need to be over 4 metres long. It also has a wide range of flue bends and extensions providing greater flexibility in positioning your boiler, however this may be less aesthetically pleasing due to the amount of pipe work on show.

 

F&E Tank

Usually found in the loft; traditional systems use two. One feeds fresh water to the hot water storage cylinder and the other one (usually smaller) maintains the correct level of water in the heating system. They also allow for expansion of the water in either when it gets hot ‚ hence the name 'feed and expansion' tank.

 

High Efficiency (condensing)

 

All High Efficiency boilers are environmentally friendly and operate at up to 96% efficiency compared to standard boilers at around 80% efficiency. They recover heat that is normally lost into the atmosphere via the flue gases. Installation: Depending on the model, your boiler may be wall mounted, floor standing or hidden away in a fireplace. Many wall-mounted boilers are small enough to be concealed in a kitchen wall cupboard.

 

Open Vented

If your heating system has a feed and expansion tank (see above) then it's called 'open vented' hot water. A hot water storage cylinder may also be open vented.

 

Output

The output ratings of boilers are measured in BTU's (British Thermal Units) or kW (Kilowatts). A low output would be 30/60,000 BTU's (10-17kW). A high output would be 60/100,000 BTU's (17-30kW). Your installer should choose the output best suited to the size of your heating system, the type of property and, in the case of a combination boiler, the amount of hot water you require.

 

Sealed System

If you have a sealed (heating) system there's no feed and expansion tank (see F&E tank) in the loft space. Instead it's filled with water via a temporary connection and expansion is accommodated by a special vessel, which may be inside the boiler. (See also expansion vessel.)

 

SEDBUK

All Baxi products are listed on the SEDBUK Boiler Efficiency Database. This Government database lists the Seasonal Efficiency of all Domestic Boilers in the UK. For full details visit www.sedbuk.com.

 

Storage Cylinder

The storage cylinder supplies hot water for domestic use and is heated by the boiler. When the hot water in the storage cylinder has been used up it is refilled by the feed and expansion tank. (See F&E tank.)

 

System

A 'system' is the term used to describe the boiler and all of the components required to provide your home with heating and hot water.

 

Unvented

The term 'unvented' most commonly refers to cylinders storing and supplying hot water at mains pressure rather than via an F&E tank and therefore at flow rates which are usually far superior.
