A gas boiler, fuelled with natural gas, oil, LPG or propane (etc), is the most common kind of appliance used for central heating in Bayston Hill and throughout the United Kingdom. It heats water which flows through pipes or a radiator, and it is used for hot water in the home as well as for a central heating system. It is also used for radiant floor heating systems. An annual boiler inspection and maintenance check by a registered “Gas Safe” gas boiler service heating engineer is essential for safety and comply with UK Law.
The Engineer will make sure that the heating system is installed according to regulations during the annual central heating and boiler inspection, that it is safe and it is working efficiently according to the manufacturers’ instructions. If this is done properly every year, gas boiler breakdowns and the resulting emergency repair work can often be avoided.
Bayston Hill High Energy Efficiency Combi Boiler Inspection – A Number of Things You Will Want to Know
Combi boilers have a lot of advantages over conventional boilers, but also a few small drawbacks. This article will open your eyes to the things you should consider when purchasing a cheaper model. There are many models of combi boilers available in the market, and like in every other product, the price usually matches the quality and determines the results (you get what you pay for).
1) Possible scaling of the DHW heat exchanger
If the water company in your area, supplies you with hard water, chances are that your DHW heat exchanger will scale with time. In that scenario, you will have two choices; either replace it with an original piece from the manufacturer (which won't be cheap), or replace the whole boiler. Of course this problem can occur with any conventional tank as well, as this is one of the effects of hard waters. The latest and more expensive combi boilers are already designed to reduce scaling as much as possible. Another thing you could do is run softened water through it, but that would definitely invalidate your warranty.
2) No option of electric immersion heater
With a conventional water storage tank, if for some reason the boiler fails, you have the option of using an emergency electric immersion heater. But the combi boiler is tankless and this option would not be valid.
3)Possible incompatibility between gas pipes
You may need to upgrade the gas supply pipe, because the diameter may not comply with the regulations for installing combi boilers.
4)Good showers, slower baths
Although one of the combis' strengths is to be able to deliver high pressurized water in both your hot and cold taps, a cheaper model may have a modest flow rate of hot water. That is no problem if you are a shower person, because it will supply just what you need to take a nice hot shower. Nevertheless, it maybe a little slower for your bathtub to fill up.
5)It does not deliver instant hot water to all taps
If the boiler is far away from the tap you are using, it may take a few minutes for the hot water to come through, as it has to travel through many meters of cold water filled pipes. This is not a problem when filling up a tub or taking a shower, but if you just want instant hot water to wash your hands or fill up a basin, it may be irritating to have to wait and see an amount of cold water being wasted down the drain.
Gas Fired Condensing Boilers
Worcester-Bosch are undoubtedly one of the leading manufacturers of gas fired boilers in the UK, with a rich history spanning 50 years of production, Worcester are one the household names to look for when purchasing a new gas boiler for your home.
In August 2012, Worcester announced the launch (although to many say it was a revision) of the new Greenstar CDi Classic Combination Boiler Range.
A total of 8 models of boilers have been launched, they are:
Greenstar 29Cdi Classic - (Formerly Greenstar 27Cdi)
Greenstar 34Cdi Classic - (Formerly Greenstar 30Cdi)
Greenstar 38Cdi Classic- (Formerly Greenstar 37Cdi)
Greenstar 42Cdi Classic - (Formerly Greenstar 42Cdi)
All models are available in either standard natural gas, or in an LPG option for those in remote locations.
So What's The Difference?
Most notably, the Greenstar Classic range have had a whole host of internal upgrades and improvements with the clever introduction of a more energy efficient standby mode. With consumers continually looking at ways to reduce their energy consumption within the home, Worcester have managed to reduce the standby electricity output of the CDi boilers from 9W to just 3.5W in the new CDi Classic Boilers.
This enables customers to benefit from a more energy efficient source of heating and hot water, which will have a positive impact on electricity bills. Therefore keeping a high standard in energy efficiency and maintaining the SEBUK A-Rated performance values in excess of 90% efficient.
The overall outputs of 27kW, 30kW and 37kW within the CDi range have been upgraded to 29kW, 34kW and 38kW in a move which substantially improves performance in flow rates, giving better hot water service to bathrooms and kitchens.
In addition to this increase in performance and reduction in energy consumption, the everyday operation has not been overlooked in this overhaul. The introduction of a magnetic flap access panel has greatly improved upon the Greenstar CDi's original push and click mechanism, a feature which often failed with many years of use.
With peace of mind and reduced costs on everyone's minds, Worcester haven't scrimped on the warranty either, with a current promotion of a full 5 Year parts and labour warranty on the boiler and a huge 10 Year Warranty on the primary heat exchanger.
Some features and benefits at a glance:
- Best boiler efficiency rating SEDBUK band A
- Fully condensing in both central heating and domestic hot water modes
- Keep hot facility - instantly available hot water
- Extremely small standby electrical output of 3.5W - energy efficient
- Wall mounting frame allows pipework to be hidden from view

With the introduction of the new Greenstar Classic Combination boilers in 2012, Worcester's continued program of improvements ensures they remain the UK's favoured choice for boiler manufacturer, there is no better time to purchase a combi boiler to reduce bills and save energy.
For Bayston Hill Systems We Often Advise Buying From The Our Recommended Combi Boiler Range
There comes a time in every homeowner's life when they must wrestle with the decision of whether or not they should repair their existing heating system, or bite the bullet and purchase a new one. Boilers and furnaces are one of the most expensive pieces of equipment in your home, so naturally you want to get as many years of service out of them as possible. Yet some times, it just doesn't make sense to make small repairs on a unit well past its prime.
The best way to prolong your system's lifespan is to ensure you have your system professionally serviced annually. This will help ensure the unit is running at maximum efficiency. It will also ensure that small problems are brought to light before they become larger expenses. However, when problems do come up, consider the following:
Is the problem easily fixable?There are many components of a HVAC unit that can easily be replaced; yet when some parts go it is much more difficult to fix. For example, ignition modules, thermocouples, or zone controls are all components that are easily replaced on heating systems. Yet, when a section of your boiler cracks, there is not much you can do except purchase a new unit.
Likewise, on air conditioners and heat pumps - many things can go wrong which are fixable. But when the evaporator coil or the condenser fails they are not easily repaired. And one of these parts needs to be replaced, it is best to replace the other with a compatible unit. Coils and condensers which are not matched can function together, but will not run optimally. Mismatched units will show decreases in performance, increased energy use, and premature system failure. So despite the higher initial cost, it is a smarter move to replace both components at the same time for maximum efficiency and prolonged equipment life.
Is the equipment inefficient?Another point of consideration is whether or not it pays to keep an outdated piece of equipment running in your home. If your boiler or furnace is over 15 years old, the efficiency is probably somewhere between 50-75%. Newer high efficiency models are between 85-95% efficient. Replacing an outdated unit with a new high efficiency model will save you money on your fuel bill.
What can go wrong next? If you have an older piece of equipment, you also must consider what may go wrong next. Making multiple small repairs can add up fast. If your unit is fixable, but the cost of repair is high, you may want to consider replacement. While it will be more expensive up front, you will save money in small repairs down the road, as well as save yourself a few headaches.
