Description

Small footprint, permanent installation. This is where propane stops being a consumable you fetch and starts being a utility you own.

It will run one serious load properly; asking it to carry heating as well is where owners get caught out.

Filled to the 80% limit this vessel holds about 96 gallons of propane — roughly 9 million BTU, or about 407 lb of product. On a 30,000 BTU/hr appliance that is around 293 hours of burn time from a full fill.

The next size down is 100 gallons and the next up is 200. Stepping up costs less than most people assume once freight is counted only once.

Siting and installation

Above-ground siting is the straightforward option: no excavation, no anode bag, and every valve and the gauge are reachable without opening a dome. It sits on legs or saddles on a level pad and can be inspected in place for the whole of its service life.

Installation is a licensed trade. We will get the vessel to your site on an insured carrier; setting, connecting and commissioning it is work for a qualified propane contractor.

Condition and documentation

The exact condition and specification are confirmed in writing before you pay, along with the test record for the vessel itself.

We check the relief valve, the service and fill connections and the float gauge on every unit. These are the parts that fail first and the parts that matter most.

Before you order

Tell us the delivery ZIP when you enquire and we will quote the tank and the freight in the same reply, including any access surcharge — not after you have paid.

Ask what the regulator and first-stage arrangement will be. The tank is only half the specification, and the wrong regulator will starve appliances the vessel could easily supply.

Talk to the sales desk

Tell us the load and the ZIP. We will quote the tank and the freight together.

No call centre and no quote-chasing — you get a real figure, in writing, from someone who knows what a lift gate costs in your county.
