DETAILS
A water heating battery is for heating air in ventilation systems with circular ducts.
Aluzinc-coated casing, heat transmission element with copper tubes and aluminium fins.Removable cover for cleaning the unit.
The water-heating battery can be installed in a horizontal or a vertical duct with an optional direction of airflow.
Max operating temperature of 150 °C
Max operating pressure 1,6 MPa (16Bar)
2-rows battery
Water connecting
When connecting a heater to the water system, the following things should be considered:1. The heater must be connected with clamping ring connectors.
2. The connecting pipes from the heat exchanger must under no circumstances be subjected to twisting or bending stresses when assembling the pipe connectors etc. Use suitable tools to counteract the twisting/bending moments during assembly.
3. Ensure that forces due to expansion in the system and the intrinsic weight of the piping system itself do not put loads on to the heat exchanger.
4. The water inlet should normally be connected to the lowest pipe connector in order to facilitate venting of the heat exchanger. A venting valve should normally be installed near the heat exchanger or at the highest point in the system.
5. The heater must be connected in such a way that the system is easy to empty in the event of repair work, a longer operational stop, or when there is a risk of freezing, etc.
6. Immediately after the system has been filled with water, the duct heater and its connections must be checked for water leaks. Leaks can cause water damage.Operational data:
Max. operating temperature: 150°C
Max. operating pressure: 1,6 MPa (16 Bar)WARNING!! If the water in the heat exchanger freezes, then it can burst, if this is the case water may leak from the system and cause water damage.If there is a risk of frost the heater must be installed with a circulation pump in a secondary circuit to ensure that a constant flow is achieved in the heater.
A frost protection thermostat or regulator with automatic frost protection must also be installed to shut off the fans and outside air damper in the system, and possibly switch on an alarm.
Cleaning
The heat exchanger must be cleaned regularly in order to retain the best performance from the heater. The cleaning interval depends entirely on the cleanliness of the air and how the filter and remainder of the system are maintained.
The heat exchanger is readily accessible for cleaning when the cover on the heater is removed. First, the air entry side of the heat exchanger is cleaned with a brush and then the whole heat exchanger can be cleaned with compressed air, water or steam.
The dirt is blown or washed away in a direction away from the exit side towards the entry side. Cleaning is facilitated by using a mild detergent (check first that the detergent does not have a detrimental effect on copper and aluminium).
Be careful not to damage the thin fins on the heat exchanger.
Mounting
The heater is designed to be inserted into standard spiral ducting and is fixed to the ducting with screws.
The heater should not be fitted too close to a fan outlet or a bend in the ducting because then there is a risk that the airflow through the heat exchanger is uneven which can result in lower efficiency.
An effective filter is recommended in the system to reduce maintenance work. See under the heading Cleaning.
The duct heater can be fitted in a horizontal or a vertical duct with an optional direction of airflow. To facilitate venting of the heat exchanger, the unit should be fitted with the longitudinal tubes horizontal. The heater is normally fitted after the fan. However it can be fitted before the fan, but then a check must be made that the fan motor and other components are approved for the elevated temperature after the heater.

Jeffrey TannerDate Added: Friday 02 November, 2012
I bought this to replace a home made unit which leaked. unfortunately it does not transfer enough heat to the ducting and causes my heat pump to keep going into fault mode. Very disappointing for the price as not useable.

Thank you for your question. Please click on the link below for the information required.
Replied by i-sells, 17-07-2015#2Heating capacityHi. The data sheet does not give details of the heat transfer of this unit. Is there a chart of heat transfer vs. the Delta T and air flow for this unit and the 200mm one please
Question by David Buckley, 22-11-2015Hello David,
Please see this additional datasheet here
This datasheet contains additional information on page 2 - Please refer to the data for VBC160.
Kind regards,
MichaelReplied by i-sells, 23-11-2015#3200mm Water Heating Battery queryVarious places on your web site imply there is a 200mm version - but I cannot locate it can you point me in the right direction? I am looking at using one of these fed from an ASHP warming the air for a MVHR system. I have looked at the downloads for the 160mm version (which also cover the 200mm) but wondered if there is any data for lower water temperatures such as at 35/25C? Finally is there a condensation drain in the unit for when warm air hits cold water pipes?
Question by Dr Paul L M Hoyle, 01-12-2021Good morning. Take a look at part numbers QS9721 and QS38779. The first part number is for just the heater, and the second is a kit, which includes controls
