More about this product
The TankBoost is an all-in-one system consisting of a water storage tank and an integrated submerged pump. It offers up to 3.0 Bar and 80L/min – ultimately, delivering an impressive level of water pressure and flow, even when multiple outlets are in use.
Salamander’s TankBoost has been designed specifically to improve the delivery of cold water in a mains-fed system, however it may also be used alongside unvented cylinders and combi boilers, increasing the cold water flow rates and pressure to any mains hot water system. It is important to note that this may restrict the flow rate of hot water that can be produced.

Frequently Asked Questions
Quick answers to common questions about the Salamander TankBoost 450L TNK-450-SUB. For technical specifications, see the product details above; for sizing or installation advice, contact our team. If you have any other questions, we're happy to help.
What is a mains pressure boosting system?
A mains pressure boosting system increases the pressure and flow of water from the incoming mains supply into a property. It typically combines a pump and a storage or expansion tank, drawing water from the mains and delivering it to taps, showers and appliances at a stronger, more consistent pressure. They are used where the incoming mains is too weak to serve modern outlets reliably.
When do I need a mains booster pump?
You normally need a mains booster if static mains pressure is below 1.5 to 2 bar, if showers run weakly when other taps are open, or if combi boilers struggle to deliver hot water. Anglian Pumping recommends checking static pressure at the stop tap before specifying a system, then choosing a model rated for the number of bathrooms and outlets in the property.
What size mains booster do I need for my home?
Sizing depends on the number of bathrooms, the type of fittings and the static mains pressure. As a guide, a 1 to 2 bathroom property with combi boiler or single shower often needs 1.6 to 3 bar boost. A 2 to 3 bathroom property typically needs 3 to 4.5 bar with an integral break tank. Larger homes need a tank-and-pump system such as the DAB Esybox with Esytank or a Powertank set.
