A tundish is required under regulation on the discharge from the safety valve. This provides both the required air gap and also a means of identifying whether the unit is discharging and has a fault.

Yes a 1.2 kW element is available in the 10 and 15L models for where a lower kW loading is required, such as temporary buildings or generator electrical supplies. The heat up and recovery times will be longer.

The Speedflow range of products will require maintenance, this includes an annual check on the sacrificial anode as well as a safety relief valve operation test in accordance with the regulations and manufacturer’s recommendations in addition to any site specific maintenance schedule.

Access to the element, thermostat and cutout on the Speedflow SF05K, SF10K and SF15K units is made from the base of the product. There are six screws which secure the base plate, the product will need to be removed from installation and inverted in order to access the panel. This is the same on older stainless steel tank Speedflows. On current stainless steel models access is made from the front. The dark fascia sticker needs to be lifted to access the fascia screws which when removed will allow access to the element, thermostat and cutout components.

Resetting the cutout on a Speedflow will require the unit to be electrically isolated and it will require removing the product from installation. Access can then be gained via the base plate where the cutout can be located and reset. The reset button should be firmly depressed and sit slightly proud of the surround when it is correct. If the cutout has operated repeatedly or will not reset it will require replacing along with thermostat components.

Our range of Speedflow heaters can be used with a thermostatic mixing valve which will allow the stored water to be above 65°C and then mixed down to a safe temperature to the outlet/s.

The expansion vessel should be installed vertically with the connection at the bottom.

Yes, ensure the unit is installed upright with the pipework coming out of the top.

The Speedflow range of products must be installed in the vertical plane with the water connections to the top of the product.

Yes

The unit can be installed at any distance; however, temperature and flow rate will decrease as the distance to the outlet increases.

No, accessory kits are available to buy separately. See Speedflow Kits

No, a much higher capacity unit is required.

The SF3 kit must be used where expansion cannot be adequately accommodated within the cold supply pipework or where a cold water draw off is within the expansion zone.

The Sacrificial Anode is a magnesium rod that is silver in colour and attached to the underside of the element plate by a single bolt.

It is normal for the anode to become pitted and disfigured under its normal operation. Replacement should be done before the anode is at around 30% of its original size.

The discharge from the safety valve must be to a safe waste, you should consider that the temperature could exceed 98°C and be at mains pressure. Any waste fitting and pipework must be able to sustain that temperature and pressure for a prolonged period of time.

Our range of Powerflow heaters can be used with a Thermostatic mixing valve which will allow the stored water to be above 65°C and then mixed down to a safe temperature to the outlet/s.

No, the unit must be wall mounted with the connections at the base of the unit.

The Powerflow range of products must be installed in the vertical plane with the water connections to the bottom of the product.

Yes

Yes a 1kW element is available for where a lower kW loading is required, such as temporary buildings or generator electrical supplies. The heat up and recovery times will be longer.

The unit can be installed at any distance; however, temperature and flow rate will decrease as the distance to the outlet increases.

Yes

The unit has detected boil dry conditions. The temperature sensor has detected a temperature well above boiling which can only occur when water is not present.

There is a problem with the temperature sensor, either open circuit or short circuit. Check the probe is connected to the board correctly, if it is then a replacement thermistor and/ or board is required.

Yes, the required part is HDYTAP.

The tap will drip during the heating cycle. This is normal as the unit vents through the tap.

Yes, the tap alone is part code HFTAPQ

No, this is intended for use with the supplied tap only. Use with another tap will void the warranty.

The hoses allow the correct connection’s to be made to the heater in order to facilitate venting of the heater.

No, the Zen Life must be installed over a sink

Yes, the Zen Solo

Yes, see the Zen Ice tap range

The Zen Life

Yes, standard boiling tank size is 3L but a 6L tank is available for larger capacity environments.

Black and white

Polished chrome and brushed nickel as standard. Black is available at an additional cost.

The Zen Spa 2 in 1 boiling and chilled tap. If specifically chilled water is desired a Sapphire undersink chiller can be installed.

The Zen Solo, Zen Spa, Zen Ice Solo, Zen Ice Spa and Crystal Pure are all ideal for use with the Zen Font.

A font is used for installing a Zen or Crystal Pure tap where access to a sink is unavailable or not desired.

Mixers and thermostatic taps are not suitable for instantaneous heaters. These heaters are for use with spray head taps with M22/ M24 spray nozzles.

No

Flow rate too high or outside of heater specification.

Flow rate too low, or heater temperature setting too high.

No, this is an instantaneous water heater. Water is heated as it passes through the unit.

The flow rate needs to be governed to achieve the correct temperature. It must be greater than 2.5LPM. If it is below this check the inline filters and tap outlets for debris or blockages.

E1 means a failed temperature sensor of water outlet. Replacement required.

E2 means a failed temperature sensor of water inlet. Replacement required.

LP means low pressure. The flow sensor has failed to detect the actual water pressure. A possible cause of this is impurities have attached to the turbo, stopping it from working correctly. When the appliance has been installed water must be flushed through first to remove any dirt/ impurities. To resolve, remove the turbo and clean it, if this is unsuccessful a replacement turbo may be required.

No

Mixers and thermostatic taps are not suitable for instantaneous heaters. These heaters are for use with spray head taps with M22/ M24 spray nozzles.

No

No, this is suitable for handwashing at a single basins only. For a kitchen sink consider a Speedflow or Aquila water heater.

No, this is a single outlet water heater.

Flow rate too high or outside of heater specification.

Flow rate too low, or heater temperature setting too high.

No, this is an instantaneous water heater. Water is heated as it passes through the unit.

The flow rate needs to be governed to achieve the correct temperature. It must be greater than 2.5LPM. If it is below this check the inline filters and tap outlets for debris or blockages.

No, the spout supplied is the only length available.

The heater can be programmed using the inbuilt timer. It has two main heat settings Comfort and Eco. It also has a frost protection mode which is factory set at 7°C. The settings and heating times can be selected from a range of pre-programmed profiles or the user can create a suitable profile. To program the unit, briefly press the P/PROG button, then using the up / down arrows select the desired program.

The main difference is that electric radiators use a combination of radiant and convection heat whereas panel heaters heat only through convection (using hot elements and a fan to blow the heated air around the room).

The heater has an in built timer which can be set for both Manual and Auto operation.
