The Grant Vortex Eco WH External Oil System Boiler range are an externally wall hung oil boiler ideal for small to medium size properties in rural areas without a mains gas supply. The Vortex Eco WH External Oil System Boilers feature the patented vortex stainless steel heat exchanger and tubular baffle system. Also the system model feature a factory fitted expansion vessel, filling loop, pressure gauge, automatic air vent, pressure relief valve abd circulating pump. Plus the Vortex Eco WH External Oil System Boilers come with a factory fitted flue and are finished in a robust powder coated painted case and built in frost protection protecting the boiler from the elements.
At Boilers2go we recommend the Grant Vortex Eco 12/16 WH External Oil System Boiler for small to medium size properties in rural areas without a mains gas supply. The Vortex Eco 12/16 WH External Oil Regular Boiler is also a condensing boiler able to help reduce fuel bills and carbon emissions by reclaiming latent heat from the flue gases. Plus the Vortex Eco 12/16 WH External Oil Regular Boiler comes with a 2 year manufacturer's warranty for peace of mind.
The Potterton Paramount Three Gas Regular Boiler is a range of highly efficient commercial boilers featuring the latest in heating technology including a highly reliable aluminium/silicone alloy heat exchanger. The aluminium/silicone heat exchanger ensures maximum heat transfer to the central heating and hot water systems and comes with an industry leading 10 year warranty. As well as providing an impressively high energy efficiency the Paramount Three Commercial Gas Regular Boilers also generate ultra low NOx emissions making this an extremely environmentally friendly option for any commercial requirement.
The Potterton Paramount Three Commercial Gas Regular Boilers also features a user friendly and comprehensive boiler/user interface, which has been developed alongside leading heating control manufacturer siemens, called the ISR Plus. The control panel for the Paramount Three Commercial Gas Regular Boiler offers a full text display of the boilers operational status and with a built in weather compensation, summer/winter changeover and time control facilities for heating and hot water makes this a highly flexible and efficient boiler.
The ISR Plus can be used with any existing compatible room thermostats or fully intergrated Building Energy Management System for additional control. The remote status facilities are built into the Paramount Three Commercial Gas Regular Boiler for run and fault signals and the ISR Plus also allows for remote control of the set point temperatures using a 0-10V signal. In addition the Paramount Three Commercial Gas Regular Boiler is compatible with a range of optional potterton controllers for Domestic Hot Water operation , optimisation zone control and modular boiler sequence control.
Key Features and Benefits:
In a closed central heating system water cannot be compressed so any increase in the volume, created by an increase in temperature, needs to be accomodated. This is done with the use of an expansion vessel, when the water in the system is cold the pre-charge pressure of the system forces a diaphram in the expansion vessel against the tank towards the inlet. As the temperature increases the expanding water volume pushes against the diaphragm creating additional volume for the water to enter the expansion vessel. As the temperature decreases the pre-charge pressure forces the water from the expansion vessel back into the central heating system. This maintains a constant pressure within the central heating system and helps to reduce energy and water consumption.
The Honeywell DT90E Wired Digital Thermostat provides automatic temperature control over gas or oil fired boiler systems, underfloor heating, electric heating and zoning systems. The DT90E Wired Digital Thermostat features an ECO button an energy saving function that gives timed setback or boosts temperatures to reduce energy demand.
The Honeywell DT90E Wired Digital Thermostat is also a TPI (Time Proportional Integral) control product, as defined in the building regulations, which makes boilers operate more efficiently and provide close accurate control. Also the 'OFF' setting can be utilised for frost and hypothermia protection, assuming the system time control is also switched on.
