Unvented Water Heaters

Whether you have a residential or commercial property, an unvented water heater is an excellent solution for your heated water needs. The difference between an unvented water heater and a vented heater is that unvented boilers utilise a sealed system. Therefore, this particular system is dependent on the installation of an expansion vessel. The unvented water heater is cost-effective and is ideal for small or medium-sized businesses due to the flexibility of installation. The water heater produces mains pressure hot water and a balanced supply of output to each outlet it supplies. There is also no need for a separate cold water cistern. Each manufacturer produces heaters designed to operate reliably under the increased pressure produced by high temperatures.
