Hot Water Storage Tanks

Overview

A hot water storage tank is only as good as the heat it keeps. We build vertical and horizontal storage tanks in stainless and mild steel, insulated and clad to suit the installation, with nozzle positions set by your system layout rather than by a catalogue drawing.

Tanks are fabricated to the capacity, diameter and height your plant room allows. Where a tank has to pass through a doorway, up a stairwell or onto a terrace by crane, we design around that access constraint before cutting material.

Specification at a glance

Capacity200 to 20,000 litres as standard. Larger capacities built to order.
OrientationVertical or horizontal
InsulationPUF or rockwool, thickness to suit the duty. Cladding in stainless steel, aluminium or powder-coated MS.
ConnectionsNozzle schedule, sizes and positions built to your drawing
FinishMill, brushed, polished or clad, specified per order
TestingScope agreed at order stage and recorded

Dimensions, thicknesses and ratings are confirmed at engineering stage against your duty. We do not publish generic figures.

Key features

Insulation and cladding specified for the operating temperature, not a fixed default
Inlet, outlet, drain, vent and sensor pockets positioned to your system drawing
Internal finish selected for potable, process or general service duty
Legs, skirt or saddle supports engineered for the mounting surface
Sized around real site access — doorways, stairwells, terrace lifts
Manhole and inspection openings where the duty calls for internal access

What we can change

Non-standard diameter-to-height ratio for low plant rooms
Additional nozzles, thermowells and sensor pockets
Multiple tanks in a matched set for staged storage
Internal baffles or diffusers for stratified storage
Branded, plain or mirror-polished external finish

Enquire about hot water storage tanks

Send us the capacity, the medium and where the tank has to go. If you have a drawing, even better. If you have none of that yet, send what you do know — most enquiries start that way.

Common questions

It depends on peak demand rather than total daily use — how much hot water is drawn in the busiest hour. Send us your fixture count or occupancy and we will work through it with you.

Yes. Tell us the make, flow and return temperatures and the connection sizes, and we build the nozzle layout to match.

Stainless for potable water and long service life; mild steel with suitable internal treatment where the duty allows and budget is tighter. We will tell you honestly which fits your case.

PUF or rockwool with an outer cladding. Thickness is set by operating temperature and how much standing heat loss you can accept.
