When the boiler senses a temperature drop to below 5 degrees it will fire up and warm itself up, this will continue until the temperature rises. Should there be a disruption to the gas supply the boiler will run the pump only in an effort to stop the water freezing within the boiler.
Our main range of boilers are, please visit the EST website for more information: http://www.energysavingtrust.org.uk/
After a period of 24 hours of inactivity, our boilers energise the pump and motorised diverter within the boiler, to ensure they don't seize. Dirt and debris within heating systems can settle in these areas, so it's important to protect these moving parts.
This question arises quite often and is not an easy question to answer. Radiators have outputs ranging from a couple of hundred watts to multiple kilowatts. A boiler with 30kw output to the heating system can supply 30 1kw output radiators. The correct way to solve this question is to calculate the total output for the radiators in the property and then source a boiler of sufficient size to comfortably support the heat output requirements. If you are having a system designed from new then your heating engineer can help source the correct radiators and boiler to ensure the correct comfort levels are achieved in each room of your home.
We would not recommend this, leaving a heating system empty for long periods will allow rust within the radiators to build up and cause components within the boiler to seize. You would also then have to refill the system upon return and ensure you have the correct amount of quality inhibitor and protector within the system. Leaving our boilers on standby will allow the boiler to look after the system for you.
All boilers are tested at given flow rates, when we say our flow rate is based on 35 degrees celsius rise, we are stating the cold water temperature will be raised by 35 degrees celsius. Others use 25 degrees celsius to try to achieve a better flow rate because the lower temperature of the water allows more water to flow through the heat exchanger. This improves the flow rate on paper but during the winter months when the water coming out of the ground is 2 or 3 degrees celsius your hot water will not be hot enough.
The boiler has a pump overrun facility that ensures any latent heat within the boilers heat exchanger is moved into the heating circuit.
Yes, all Biasi boilers can be range rated on the heating output. On the Inovia and Advance Plus boilers you also have the option in the software to range rate the maximum flow temperature.
The Inovia and Advance Plus can both use 230 volt and volt free switching external controls. This will facilitate a range of old, right through to the latest RF type external devices. For guidance on the connection of any such device please feel free to contact our service and technical staff on 01922714636.
Yes, all Biasi boilers are LPG convertable and all have LPG conversion kits available.
All Biasi boiler ranges have available a rear pipe hiding kit known as a stand off kit or stand off bracket. This accessory allows the pipework to be taken up directly behind the boiler.
The Advance Plus and Inovia range of combination boilers both have a two stage weather compensation system available and an advanced function modulating room thermostat. First stage is the addition of the outside air temperature sensor which will facilitate basic weather compensation. The second stage is the addition of the Biasi Stat which will then allow full self learning and self compensation weather slope adjustment.
Yes our boilers can operate on low pressure. Although we would always recommend a primary system pressure of between 1 and 1.5bar when cold, the boiler will operate once the system is above 0.3bar. The domestic hot water will operate as low as 2.5 L/min at 0.3 bar.
All current Biasi boilers are compartment ventilation free, for older models please refer to either the manufacturers instructions for that boiler or contact the Biasi service and technical office on 01922714636 or firstname.lastname@example.org for guidance.
On the Riva range of boilers the serial number can be found on the drop down flap. For Inovia and Advance Plus there is a small grey sticker in the front of the boiler. The serial number starts with N and the last four digits represent the month and year the boiler was produced.
The industry standard is 8 years but we still hold spares for 12 years and beyond.
Every boiler manufacturer will insist the boiler is serviced annually in order to maintain your warranty. Just like a car, if you run the boiler when its not been tuned properly you risk putting it under stress. With anything electrical or mechanical, stress will reduce the life of the boiler. Small issues soon become big issues and can often lead to large repair bills, likewise the efficiencies could also be effected meaning you waste energy and money. Most important to Biasi is safety. By having a regular inspection you will have peace of mind knowing your boiler is working safely and efficiently.
The spanner symbol will appear in isolation when your boiler is due for a service. If you have recently had your boiler serviced and the engineer has not reset the spanner please contact our service and technical department who will talk you through what to do next.
If you are having to top up the pressure on your system on a regular basis, there is something wrong with the system and we would recommend calling a heating engineer to see if they can identify the issue.
Type 11 is a single convector and a single panel radiator, type 21 is a single convector in a double panel radiator. Type 22 is 2 convectors in a double panel radiator.
Yes, it is possible to do this with the radiators in situ, the side panels will push up providing the locking clips are in the correct open position.
Lack of a quality inhibitor, fresh oxygenated water and electrolyses will all cause radiators to leak. There is no such thing as a bad batch of radiators. If your system is developing leaks there will be a reason and that reason is usually a problem with your heating system. Dirty black water is the first sign, constant topping up of the water within the system is another sign along with over pumping on open systems.
There are companies who bend radiators but please note if this is done your warranty will no longer be valid.
Everything that is required for installation, with the exception of the radiator valves can be found within the packaging. Two brackets (3 on rads over 1600 long) Plastic inserts to minimise expansion and contraction noise, an air vent and plug.
Each radiator has 4 x 1/2 connection as standard.
There are two forms of heating, radiation and convection. Chrome has poor radiation properties so you lose the added heat that you would gain from radiation, which is normally 25 - 30% of the output for the same size in white. This is the case for every manufacturer using chrome or powder coated white paint on steel.
Yes you can but you need to leave enough space for the expansion of the water.
A dual fuel installation is where your towel rail is heated via your normal central heating but also has an electric element, so that during the summer months, when your central heating is off, you can still warm your towels.
No, they are made of steel and fresh oxygenated water will cause the towel rails to rust through.
To find the pipe centres you need to take 44mm (22mm per side) off the total width of the towel rail, so a 600mm wide towel rail will have pipe centres of 556mm.
There is no real hard and fast rule but clearly you want to leave as much space as possible for towels. 10mm from the upright bars and two tubes down/up from the top/bottom looks best.
Standard efficiency boilers waste heat within the exhaust flue gasses whereas high efficiency are lower causing the flue gasses to condense and turn into water. SE flue kits are made of metal to withstand the heat but HE are plastic to withstand the acid water produced when condensing. The water produced by HE boilers will eat through the metal. The heat produced by SE boilers would melt the plastic so its important to get the right boiler accessories for your boiler.
No, all flues are tested and certified for each boiler. Using different or even worse mixed flue parts not only puts the customer in danger it would also invalidate your warranty.
No with exception of the roof terminal, all flue sections need to be kept within the building.
All our boilers are different, the less restriction within the boiler the longer the flue can be run. Please refer to the technical pages of your chosen boiler. If you are unsure please send a diagram to our technical department who will be happy to check this over.
We still keep some flue accessories for replacement market purposes, speak to your local merchant for details.
Calculate the number of people in your property by 35 to 75 litres of water per day (the quantity depends on the type of water usage such as showers or baths etc). Seeking guidance from a professional heating engineer is always recommended.
Providing the loft rafters are strong enough and also fully boarded to provide sufficient support and the roof has sufficient height then yes. The weight of the cylinder when full is dry weight plus 1kg per volume litre, for example the 250 direct model is 49kg + 250kg volume so 299kg. If height is a problem then consider using two shorter cylinders connected in parallel.
Regulations state that in areas where the hardness is above 200ppm a form of scale prevention device should be used. The cylinders have smooth coils so that scale does not have a very good foothold and the provision of a bottom drain enables a full descale to be undertaken if necessary
A minimum of a 22mm mains water feed pipe with a minimum of 1.5bar pressure and a minimum 25L/min flow rate is required.
No. Only installers that have trained and attained a special qualification are able to install and self certify the installation to building control.
An average of 2kw of heat energy over a 24 hour period is lost.
The cylinders are provided with all the equipment it requires to comply with Building regulations part G3. Only an additional drain valve or blanking plug is required for the bottom drain point.
Yes this is not a problem and is quite common. By installing a Biasi Solar Cylinder you will have the ability to add solar to it at a later date.
Yes, ensure that the cylinder and its ancillary components are protected but at the same time accessible for maintenance.
Yes, its extremely important to have unvented cylinders serviced every year. Some of the ancillary equipment can fail as a result of not receiving annual servicing. It is also important that the relevant service record is completed each and every time.
