50 kW Gas Boiler
Our 50kW boiler which are a gas boiler powered by either natural gas or propane, are ideally suited to the larger end of the domestic boiler market such as domestic use in larger homes, and lets you expand into the light commercial boiler requirements that you may have.
They are an ErP “A” rated efficiency rating condensing gas boiler with energy efficiency up to 108.8 % at 30C return temperature on the central heating system, with key features such as a stainless-steel heat exchanger, fully modulating 10:1 range – which is perfect for heat loading matching ensuring a long and efficient product life cycle and reduced running cost of your central heating system.
They are a powerful wall hung boiler and a low NOx emission gas boiler, class 6 with high energy efficiency – which means they have the least impact on the environment as well as lower energy bills and saving money. Available in natural mains gas or LPG. They can be used in a multi boiler cascade system if so required.
These are system boilers , so these boilers require an indirect hot water cylinder for your domestic hot water demands.
50kW system boiler
A system boiler, has a separate unvented cylinder for producing and storing domestic hot water. This ensures that a consistent supply of hot water can be delivered to a large number of showers and hot taps simultaneously. As a result, a its an excellent choice for a property with multiple bathrooms, that require a higher domestic hot flow rate.
System boilers do away with the requirement for a water tank in the loft since they get their water straight from the mains (which is required with a conventional boiler / heat only boiler). They then heat the water to provide warm water for the hot water cylinder as well as central heating.
You have to install a heating expansion vessel on the installation (by others) which is usual at this boiler output.
System pressure for the hot water is mains water pressure and the stored water gives an excellent flow rate, which overcomes some of the problems with combi boilers that you can have with more than one bathroom properties.
Because combi boiler they are only really meant to sustain one hot water outlet at a time, they are not well suited to households with a high demand for domestic hot water. Heating performance may well be reduced in high-usage households because combi boilers routinely switch the burner from the heating system to hot water when there is a hot water demand.
This boiler can be matched up to various sized hot water cylinders to suit the home requirements for heating and hot water outputs, with effortless comfort and using less fuel compared to an outdated, older inefficient boiler.
The hot water cylinder can also be fitted with an immersion heater for back up water heating which can be powered by a renewable source to help reduced your carbon footprint.
However, should your hot water flow rate requirement be under 20 Litres / minute, then a combi boiler could be the better option, as a combi boiler produces hot water on demand – look at our reliable combi boiler which is a wall hung 50kW combi boiler webpage for more information. A combi boiler does both heating and DHW, and is a ErP “A ” rated energy efficient for reduced running cost and gas bills. A combi boiler will also have less installation costs that a system boiler and water heater ( i.e. a hot water cylinder), but please note combi boilers of this 50 kw size require a good mains water flow rate to supply the DHW output and won’t be the right choice if you haven’t the flow rate required.
Key features of our 50 kw condensing gas boiler
Natural Gas or LPG fired
Main features – our efficient boilers are available in natural gas (mains gas) or LPG (Propane) powered units and are a great central heating boiler replacement or as a new boiler.
The gas boiler central heating output range is 49.19 kW down to 4.83 kW on an 80C/60C heating circuit, or 53.40 kW down to 5.15 kW heat output on a 50C/30C heating circuit.
Modulation up to 1:10
For greater efficiency and reduced consumption both in heating and in domestic hot water production, when used with hot water cylinders
Low Class 6 NOx emissions-
NOx is a catch-all term for nitrogen oxides, which primarily include nitric oxide (NO) and nitrogen dioxide gas (NO2), our boilers have the lowest class emissions
These wall hung gas boilers can operate on a heating circuit with a minimum pressure of 0.3 to 3 Bar maximum
All boiler sub components such as our air separator, pump etc are leading brand products and are selected through careful research for a guarantee of quality and reliability over time.
An improved display screen
Modern design with push control buttons – for easy control of this 50kW gas fired boiler. With fault codes , for fault finding if there’s ever a issue.
Unrivalled quality / price ratio
The best boiler performance at affordable prices
A wall hung boiler, with modern upgraded controls, that make it one of the most efficient and also one of the quietest boilers manufactured on the UK and Irish markets – at only 52 Decibels noise level – which makes a difference with quieter operation.
Heating output –
The gas boiler power will modulate the heat to the demand of the customers heating system installation, as the boilers output power range will go from from 50kw down to 5kW
Because the heat requirements of a gas boiler do not remain constant throughout the year owing to changing seasons, it may only be running at 20% of its capacity when it is warmer or at 80% when it is colder, our fully modulating 50kw gas boiler adapts to the heating system requirements, providing higher efficiency and reducing gas bills through wasted energy consumption.
Heating and Hot Water
Heating and hot water is provided by the boiler, via an indirect cylinder / calorifier – The heating side will heat your radiators or underfloor, whilst providing heat for the coil for the indirect cylinder
We do a range of controls that make your life easier, when it comes to controlling your boiler, from a basic room thermostat / programmer, with push control buttons all the way up to enhanced wireless internet controllers, such as Nest, Hive or bosch easycontrol thermostats, with features that provide you with the ability to regulate and control your heating from any extended location away from your home
We do a full range of flue options, such as horizontal or vertical kits, or additional flue lengths in 0.5 or 1 metre extensions that ensure installation in the home easy – they are 80 mm / 125 mm outside diameter concentric – thus room sealed
Space required for installation
This 50kw heating boiler range is compact and modern, through award winning innovation in design and operation, it is also one of the quietest boilers to date on the UK and Irish markets -allowing you to locate the unit in any room and keep you cosy in the cold winter months.
Pipework connection detail
For easier installation, service, and maintenance, all installer touchpoints have been optimized, with a system pressure gauge located in an easy to read location on the front panel of these gas boilers to show the optimum pressure which gives good peace of mind.
Frequently asked questions
How many radiators can a 50kw boiler run?
The number of radiators a 50kW output boiler can run, will depend on the property. The average sized radiator in a new build home is 1.5kW output, thus newer properties the boiler can run 30 rads to be safe. With older less insulated properties, you’re looking at around 18 to 20 rads, click here for more details
Is a higher kW boiler better?
Boiler are sized to overcome the heat loss from the property ( normally at -5C outside, to give an internal temperature of 20C) in the previous years , you could oversize a boiler, which was not good for efficiency and your fuel bill, but these days the quality end of the market ensures that the boilers are modulating, which means they will operate down to some very low outputs – our 50kW gas boiler will operate down to 4.83kW flow rate, which ensures better heat load matching of the system, with high efficiency and lower running costs , click here for more details.
Gas safe registered engineer
As always, we insist that any gas boilers are installed by a gas safe engineer, not only for the interest of safety, but also for the fact that it’s a legal requirement for the gas installation to be done by a suitable qualified person, so you can sit comfortably, knowing you heating and hot water system is safe.
