Vitoflow hydraulic balancing – the next step for improving heating system efficiency
Viessmann is the first manufacturer to offer an automatic process for balancing heat distribution for every heat source up to 150 kilowatts
Viessmann is the first manufacturer to develop an automatic hydraulic balancing process for optimising heating system efficiency. The Vitoflow technology can be applied to all the company’s gas, oil and biomass boilers, as well as heat pumps up to 150 kW and micro CHP systems. The automatic hydraulic balancing system reduces CO2emissions and can cut users’ fuel bills by up to 15 percent.
Vitoflow has been developed to ensure that the efficiency of systems keeps up with the high efficiency products that Viessmann offers, thus providing the opportunity for maximum energy savings. The latest technology means that heating water flow and pump rates are determined automatically, so every radiator is supplied with exactly the amount of heat it requires. Vitoflow can be used in any building with up to six residential units or 24 radiators.
In heating system modernisation projects, the complex calculations Vitoflow carries out come to the fore; no input on the length, diameter, or layout of pipework is needed and any unknown flow resistances are taken into account. Vitoflow technology can be applied in under an hour, meaning that there are great savings in work time and costs, compared to systems which are balanced manually.
“The advent of the mandatory fitting of thermostatic radiator valves (TRVs), which allows the adjustment of individual radiator temperatures, has resulted in the once common practice of manual balancing, being increasingly overlooked in the UK,” says Christian Engelke, technical director at Viessmann, “With such efficiency benefits to homeowners, we hope that installers see a gap in the market for automatic hydraulic balancing as an easy-to-implement ‘added value’ service to offer their customers.”
The only things that are needed to install Vitoflow automatic hydraulic balancing to a heating system are a laptop with Vitosoft 300 service software, a service case and an extension case, containing radio-controlled servomotors and a high-efficiency flow rate pump, respectively. After room-specific data, such as the heat load and type of thermostatic valves are entered into Vitosoft 300, the existing valve heads are exchanged for radio-controlled servomonitors, and if necessary, flow rate sensors and a high-efficiency pump are fitted. In under an hour the software will have determined the default settings needed for the thermostatic valves and the required pump rate. After these have been applied and the thermostatic heads re-installed, the process is complete and the Vitoflow technology will require no further human input.
