Frequently Asked Questions

  • What is the difference between the Grant Vortex boiler and the Grant VortexBlue boiler?

    The Grant Vortex boiler range uses a low NOx yellow flame burner, whereas the Grant VortexBlue boilers uses an ultra-Lox blue flame burner. The combustion head on the VortexBlue’s burner is specially designed to re-circulate the combustion gases. Re-circulating the combustion gases in this way significantly reduces NOx emissions and produces the clean blue flame which gives the technology its name.

  • What size of boiler do I need?

    Before selecting your new boiler, Grant recommend requesting that your installer performs a heat loss estimation of your home to ensure that you select the most appropriate size and type of boiler. Heat loss depends on the efficiency of any heat retaining methods that can be implemented in your home, for example loft insulation, double glazing, cavity wall insulation, draught proofing, etc. These practises could mean that your new boiler may need to be smaller than the one that it is replacing.

  • Can I run a new Grant Vortex boiler on an older heating system?

    As long as the system is thoroughly cleansed and updated to fully pumped operation, it is possible to run a Grant oil boiler on an older heating system.

  • Can I use my existing flue system for my new Grant boiler?

    Unfortunately, in most cases you will not be able to use an existing flue system with a new boiler. Condensing boilers have a lower flue gas temperature which can lead to harmful condensation in the chimney/flue. You will need to ensure that you install a Grant approved flue system which is stainless steel and sealed securely at the joints to prevent it from leaking. All Grant external modules come with a factory fitted flue system.

  • How often should a Grant boiler be serviced?

    Grant recommend that an oil boiler operating on kerosene should be serviced every twelve months, and an oil boiler operating on biofuel or gas oil should be serviced bi-annually.

  • I’m worried that my oil supply could run out, how would this affect my system?

    Grant recommend keeping your oil tank filled as required to ensure that the oil does not run out. If your oil supply does run out, you should contact a qualified oil heating engineer to bleed the system once the tank has been filled. It is recommended that after filling, a period of about an hour is allowed for any sediment that has been disturbed in the oil tank time to settle before operating the boiler. With an oil boiler, there is a risk of air and contaminants that sit in the bottom of your oil tank (water and sludge) reaching the oil line and ultimately the burner. This will affect the operation of your boiler, however maintaining an adequate oil level in the tank can prevent this from happening and causing further damage.

  • Is top access required for servicing Grant Vortex Eco Utility boilers?

    If the model installed is a standard Vortex Eco Utility boiler, top access is not required as all of the burner and combustion chambers can be accessed via the front. However, if a sealed system kit has been fitted, top access will be required.

  • Are Grant Vortex Eco Utility boilers supplied with a condensate trap?

    All of Grant’s Vortex Eco Utility boilers have a condensate trap factory fitted within the white case, mounted on the inside of the left side panel. If preferred, however, this can also be sited externally.

  • What type of pipework are Grant Vortex Eco Utility boilers compatible with?

    Grant boilers are compatible with both copper and approved plastic pipe. When installing the boiler, the first metre of pipework connected to both the heating flow and return connections of the boiler must be made of copper, whatever the type of system (sealed or open-vented).

  • How should radiators be sized to work alongside the Grant Vortex Eco Utility boiler range?

    It is recommended that engineers should size radiators with a mean water temperature of 60°C. In addition, the system controls should be set to maintain return temperatures below 55°C. By setting the heating system to work within these parameters, the boiler will be able to achieve maximum efficiency.

  • Why should a sufficient air supply be provided to the boiler?

    Ensuring that there is a sufficient air supply permanently available to boilers such as the Grant Vortex Eco Utility range is important for a various reasons. Firstly, this allows for the proper combustion of fuel and effective discharge of combustion products to the open air. And, secondly, it allows for the ventilation of space around the boiler to prevent overheating of the unit and any equipment in or near the boiler.

  • Are sealed system Grant Vortex Eco Utility boilers available?

    Grant Vortex Eco Utility Sealed System boilers are available with three sealed system models in the following outputs: 15/21kW, 21/26kW and 26/35kW. The sealed system versions include a factory-fitted expansion vessel, filling loop, pressure gauge, automatic air vent, pressure relief valve and high efficiency pump.
