Gas & Oil Heating Systems
Full Range of Modern Heating Technologies
If renewable heat technologies are not suitable, then you should consider installing a modern efficient gas or oil boiler to minimise your heating costs.
Bioheat are installers of market leading brands such as Worcester Bosch and Grant gas and oil boilers, names are synonymous with highly efficient gas and oil-fired central heating appliances throughout the UK and Ireland.
All Bioheat systems come with manufactured backed guarantees to give you peace of mind for the long term.
Bioheat’s engineers are fully trained experts and ready to optimise the efficiency of your heating system.
Bioheat tip’s for an efficient heating system:
Ensure optimal water temperature
Many properties will have high efficiency condensing boilers, however in order for these to operate in condensing mode the return temperature of the water from the building must be below 55°C. If the boiler is not operating in condensing mode, the high efficiencies the manufacturers state will not be achieved. Many systems are only designed, commissioned or controlled to deliver condensing temperatures at peak winter temperatures. In order to deliver year-round efficiency ensure your system should be designed and commissioned so that the return water temperature is below 55°C at all times.
Regular servicing and proper maintenance
Heating systems lose efficiency over time, costing you money and increasing your carbon emissions. All heating systems should be properly maintained and serviced in line with manufacturers guidelines to maintain high efficiencies.
Ensure pumps are commissioned and installed correctly
If you opt for a variable speed pump, ensure the system has been designed, commissioned and installed so that you get variable speed pumping. For this to happen the system needs to detect when each space comes to temperature, at which point the system should stop the flow (not divert it), the pump therefore sees an increase in pressure and backs off. Systems shutting down in this way also have the benefit of preventing heating water from short-circuiting back to the boilers and elevating the return temperatures (which as we’ve seen above prevents condensing taking place in your boiler).
Fill your new system with clean (treated) water
We recommend keeping oxygen, bacteria and hardness (scale) out of the water system from the very start. The industry standard is to fill, pressure test and flush new pipework systems with approximately 20 system volumes worth of water from the tap, straight into the drain. Not only is this wasteful and polluting but it also introduces oxygen, bacteria and scale to your brand new system. A build-up of any of these on heat exchanges, pumps or any other system component will mean a reduction in efficiency and potential damage to your system which, if treated correctly, should last decades.
An alternative method to the industry standard is a re-circulatory filtration system which involves filling the system from day one (before pressure testing) with treated water. Your new system can then be flushed by passing the treated water through a filtration and pumping station and back around the system. This method means no water wasted, no polluted water put into the drain and no oxygen, bacteria or scale in your system at any point.
Don’t over-size your boiler
When your system is being designed a boiler will be chosen based on peak winter conditions, a safety factor is then added followed by up to an additional 60% for heat up. The problem with this is that boilers can only be turned down to approximately 20% of their usual output, after which they will turn on and off which is highly inefficient. Question your designer to ensure the capacity of your system has been carefully specified.
Consider your metering strategy
Think carefully about your metering strategy, not just for electricity meters but heat and gas meters as well. Ensure meters are installed correctly and that they are connected to your BMS (Building Energy Management System). The collection of reliable data from day one will help with future energy efficiency improvement projects.
Ensure all the difficult components of the system are insulated as well as the straightforward pipework. This includes flange and valves, air and dirt separators and strainers. Each of these, if left uninsulated, could be costing you £20-30 a year in wasted heat, compared with an insulation jacket which could cost as little as £10. This applies to the whole system and not just the plantroom.
Get to know your Building Energy Management System (BMS)
The correct BMS is crucial for efficient operation of your heating system, however, they also need to be user friendly and fit for purpose. Ask your designer/contractor to explain what you’re going to get with your BMS and how it’s going to be controlled, are you wanting remote monitoring? Will you be tied into expensive maintenance contracts with the manufacturer? And crucially, make sure you end up with what was originally specified.
Beware of overheating plantrooms
We see this all too often and it can be down to a number of issues. Perhaps the most common is a lack of appropriate ventilation. The British standard requires both high and low level vents to allow buoyancy driven ventilation throughout the plantroom. Other factors which could contribute to overheating in the plantroom may be poorly insulated equipment or boilers running at too high a temperature. Our advice is to challenge your designer/contractor to ensure you aren’t going to have problems with an overheating plantroom, in extreme cases we’ve seen neighbouring accommodation uninhabitable which is obviously less than ideal for your business.
