System design
The type of Heating and hot water application should be one of the main principle objectives when planning a refurbishment, extension, or new build construction, even though it is normally the last thought on the part of the client, I mean you wouldn't design and build a car and give the engine no more than a second thought.
The most frequently asked question I get is "how big is it", because obviously living space is big consideration to most clients, more than their heating and hot water system, and the fact it has never been considered during the initial building design phase.
That's why choosing the type of system, testing available supplies, where it goes, how big it is, type of fuel, and ease of adding renewable forms of power either at the time or if costs do not permit in the future, should be done at the design stage.
We can work on a purely consultation basis or design and installation basis, either directly with the client or in collaboration with architects, builders, or private developers. We will ensure the system will be compliant with part L of the building regulations and more importantly meet all the customers needs in relation to performance, and energy efficiency.
We will make recommendations on system type, design, renewable†energy and water conservation.
To avoid disappointed customers/†clients contact us for free advise and costs for consultation for design and specification.
Under Floor Heating
Under floor heating is a very smart effective, and efficient form of heating for conservatories and areas where wall space is limited.
We can install various types of under floor heating in retro installation applications or for new extensions, either on solid, suspended or existing floor types.
System type
Most modern installations are what they call sealed, which means they do not require any cold water storage cisterns either for the central heating or the hot water system.
As from the 1st April 2005 all boilers installed have to be condensing.
Condensing boilers simply take more heat from the flue gases which lowers the temperature of flue gases below the due point causing the flue gases to condense which is visible as a plume of water vapour from the boiler flue. The boiler is more efficient because the boiler removes more heat from the flue gases that would normally be lost to the atmosphere.
Although condensing boilers have to be fitted to meet building regulations, they are not without problems and in my opinion are not the only solution†in lower co2 levels.
Combination boilers
Combination boilers are far the most popular boiler installed in this country, not because they are better than any other type but because they are a fairly inexpensive to install, and take up very little room.
They have limited hot water capacity and mainly suited to small domestic one bathroom properties. I.e. no bigger than a small three bed roomed semi.
Can provide flow rates of about 14L litres per min @ a rise in temperature of 35 deg centigrade.
In English that means if your cold water incoming temperature is 15 deg centigrade you would get a hot water flow of 14L/per min at 50 deg centigrade.
Disadvantages
- No immersion heater, no electric back up.
- Takes longer to fill a bath.
- Low flow rates can normally only run one hot tap at a time.
Advantages
- Inexpensive to install.
- Efficient as you only pay for the hot water you use.
- High pressure, good for showers (providing no one else turns on a hot water tap).
- Takes up very little space.
Combination boilers with stored water
A combination boiler which stores either primary water (heating water) or secondary water (hot water) to provide higher flow rates for larger properties with one bathroom and en-suite.
Although in my opinion this a compromise between a combination boiler and pressurised hot water cylinder it has the advantage of taking up less space than a pressurised cylinder, and can provide flow rates of up to 48 l/ per min. Suited to a three or four bedroom property with bathroom and en-suite.
Disadvantages
- No immersion heater, no electric back up.
- can normally only run two hot taps at a time.
- Takes up more space than a wall hung combination boiler.
Advantages
- High pressure, good for showers.
- Can run more than one tap at a time.
System boilers
A un vented heating boiler with no direct hot water heating capacity. System boilers are very versatile and can be used in conjunction with existing hot water cylinders as a means to directly replace existing conventional boilers.
System boilers can be used in conjunction with pressurised hot water cylinders or thermal stores.
Pressurised hot water cylinders
Pressurised cylinders can be used in conjunction with either existing boilers or a new condensing system boilers. They are suitable from one bedroom flats right through to 20 bedroom houses, and with a flow rate of up to 100 L/per min and pressure of up to 5 Bar they are the ultimate solution to provide hot water to larger properties with multiple bathroom installations.
Disadvantages
- Large unit takes up more space.
- Cost more than a combination boiler system.
Advantages
- High pressure, good for showers, body jets etc.
- High flow rate.
- Can run multiple hot water draw offs simultaneously.
- Electric back up.
- Secondary circulation (instant hot water at draw offs).
Multiple system zoning
Multiple system zoning is where part of a system can be controlled separately from the rest of the system for better control and efficiency.
For example a house with four floors could have all four floors independently controlled, working at different times and temperatures than the rest of the system.
Weather compensation
Weather compensation is where the boiler disides what temperature to heat the system water, using the outide weather conditions it calculates a heating flow temperature to maintain a constant internal temperature.
Together with Multiple system zoning it can make a big difference to energy consumption.
Guarantees
Our standard guarantee for plumbing and heating installations is 2Years parts and labour, our guarantee can be extended for a period up to 6 years at an additional premium, depending on work undertaken, Written details and prices can be provided on request.
We also offer an insurance backed Guarantee at an additional premium, which would cover you if we ceased trading, Written details and prices can be provided on request. In addition to our standard or extended guarantees certain manufacturers provide longer guarantee periods for example.
OSO un-vented cylinders†are guaranteed for 25 Years by the manufacturer.
Rettig Purmo Compact Radiators are guaranteed for 5 years by the manufacturer.
Our standards
All work is carried out to British standards and the relevant building regulations. Corgi will be notified that work has been undertaken and they will inform building control under part L and J of building regulations, and provide you with a certificate of compliance.
The heating system will be†Jet flushed using a sentinel jet flush machine and sentinel cleaning products. †to B.S 7953 to remove installation debris.
Only copper pipe will be used on the installation and will be cleaned externally to remove any residual flux deposits, and clipped at regular intervals.
New pipes in exposed areas will be lagged to prevent heat loss. New pipe work running through joists will be lagged to prevent friction noise.
Systems will be fully pumped and have a programmable room stat, cylinder stat, and boiler interlock, to meet building regulations part L & J.
Thermostatic radiator valves will be fitted to all radiators in all rooms, except the room where the programmable room thermostat is to be fitted, to meet building regulations part L & J.
All new condensing boilers will produce water vapour, and this will be visible as a plume from the flue. Care must be taken to flue the appliance, and agree a suitable position. A terminal guard will be fitted around the flue if it is within 2 meters above ground level.
We cannot be held responsible for any complaint once you have agreed the flue position.
The system will be commissioned to appropriate gas and building standards, and inhibitor added.
All paper work including the guarantee and boiler log book will be filled in. You will be left all boiler and control information, and installation literature, and any gas safety certificates. Corgi will provide you with a certificate of compliance which will be required for the "Home Information Pack" H.I.P. The home information pack, or sellers pack will be required by law by 2007 for anyone selling their homes.
Assessment Procedure
As from the 1st of April 2005, revised approved document L1 of the building regulations sets down revised guidance for the efficiency of hot water central heating gas and oil boilers installed in new and existing dwellings.
From that date reasonable provision would be demonstrated by using condensing boilers with a SEDBUK efficiency in band A or B, unless there are exceptional circumstances that make this impractical or too costly.
We can undertake assessment procedures for dwellings and produce exemption certification if required.
£300 rebate
On Monday 5 December 2005, the Chancellor made a pre-budget announcement regarding the Governmentís intention to offer a £300 rebate off the cost of installing a new central heating system for people aged over 60 who own or privately rent their home. The £300 rebate can only be used by householders who either have no heating system or one which is inoperable.
The £300 rebate will be made available from 11 August 2006 to all householders aged over 60 who are not in receipt of a qualifying benefit that would allow them access to the Warm Front grant of up to £2700.
The portal enables Heating Installation companies to register with the Warm Front £300 Heating Rebate Scheme. The scheme is managed by the Eaga Group on behalf of Defra.
The Eaga Group is a successful, fast growing and ambitious organisation driven by firmly rooted social and environmental principles, a commitment to employee ownership and a track record of delivering lasting social and environmental change, throughout the UK and internationally.

Fuel Poverty
What is fuel poverty? There are still houses with no or very little heating, or old types of heating systems, e.g. old style solid fuel back boilers and inefficient fires etc.
The definition of fuel poverty is when your fuel bills costs are more than 10% of your total income, are you in fuel poverty?
The government has various initiatives designed to help people who cannot afford to pay for new efficient hot water and heating systems, and eventually would like to eradicate Fuel Poverty all together, please click on the link to the Office of the Deputy Prime Minister for more information.
