The dual water boiler duel

Instanta’s DC15 can boil water to temperatures of between 70°C and 98°C.

The water boiler market has been taken by storm recently by models which offer different temperatures of water in the same unit. So with manufacturers in the sector aiming to attract distributors to buy these products, Catering Insight asked them for the lowdown.

Southport-based Instanta’s offering in this sphere is its DC15 model, which has two separate stainless steel water tanks. One side dispenses boiling water at 98°C for the brewing of regular black tea, while the other side can be set to a slightly lower temperature of around 80°C, suitable for preparing green or other speciality teas.

Sales director Graham Crisp detailed: “Dual temperature boilers are saving customers money by them only needing to invest in one boiler to dispense two different temperatures as opposed to having to purchase multiple boilers to set at different temperatures. This is a great way of saving space.

“Some of the advantages of our new DC15 are that it enables you to turn one side off during quiet times and each side displays the temperature of what can be dispensed. It has one single power and water supply.”

His advice to distributors is: “Distributors should consider the power loading and the size of the units when deciding between single and double tanked boilers as they can be a little bigger compared to single sized units. I think distributors should consider the range or variance of the temperatures required and also the accuracy of the temperature that the unit can maintain.”

Crisp believes that water boiler technology overall is heading in the direction of self-diagnostic machines and sensor dispensing.

At competitor Lincat, its own twin tank boiler range is headed by the FilterFlow EB3FX/TT. The unit is built with twin tanks that are capable of providing hot water between 70°C and 98°C. Alternatively, when required, both tanks can be set to the same temperature to meet the demand for piping hot water.

The water boiler features enhanced self-diagnostics, a narrower footprint, timer modes and longer life filter cartridges. It is equipped with what are said to be large, easy-to-use colour touch-screen displays.

MD Nick McDonald commented: “Features typically found on premium competitor models come as standard on our new range. These include a 7-day timer, which allows the boiler to be programmed to switch off overnight or at weekends to conserve energy.

“There is also a predictive Eco setting, which reduces the volume of boiling water by 50% for quieter periods. Exclusive to FilterFlow boilers, the Eco setting learns usage patterns and switches between eco mode and standard mode to deliver the required hot water output in the most economical way. There is a function too that allows users to descale the water boiler, avoiding costly engineer visits.”

He emphasised: “It is important to realise that different teas need varying water temperatures. Whilst most black and red teas need boiling water, most of the others do not. Some green and white teas for example should be made with water which has been heated to just 70°C. The improvement in flavour and fragrance of green tea made with the correct temperature of water is enormous.”

However, he acknowledged: “The downside of a twin tank boiler is a higher purchase price and a slightly reduced output, but these are small prices to pay when preparing premium quality beverages. The distributor should always recommend the most appropriate product for the customer’s needs.

“If the customer wants to offer a variety of beverages which require preparation with water at different temperatures, then offer a twin temperature model, otherwise recommend a single tank model. It is also important that the operator can easily adjust the temperature settings – the colour touch-screen of the FilterFlow range offers this facility.”

He added: “In both cases, built-in filtration is a must to ensure the highest possible quality of beverage. Effective built-in filtration can radically improve the flavour of hot beverages, by removing the sediment and impurities that can leave an unpleasant taste. It will also reduce damaging scale build up too, to prolong the life of the water boiler.”
