What should I look for apart from price?

Cylinder material - stainless steel will have a much longer life than
copper or cast iron.

If the cylinder is fitted with an anti-corrosion anode, is it
replaceable? An anode is not required for stainless cylinders because of
the inherent very high resistance to corrosion. However, an anode is
highly desirable on copper cylinders. On cheap copper cylinders, the
anode may be non replaceable, which means the cylinders potentially have
a short life as corrosion will begin once the anode is exhausted.

Does the cylinder take standard size immersion heaters? If your
heater/thermostat fails, it's helpful if you can get a replacement.
Again, some manufacturers use unusual size heaters, which may be
difficult or impossible to obtain in later years, if the cylinder model
is discontinued.

How much insulation is on the tank, and what is the standing heat loss
(in kWh per day)? Are versions available with extra factory fitted
insulation?

If you're using an indirect cylinder, what is the reheat rate?

Don't buy one at all. You need a BBA approved fitter and an annual service
charge of £60-100 per ann.

Get a heat bank. The Pandora http://www.heatweb.co.uk doesn't even need an
overflow pipe.
Look at:

No annual service charge and performance the same if not better. The range
units can have the CH run of the cylinder too.

Or look at a Rinnai high flow two bathroom multi-point. Far cheaper than an
unvented cylinder. Very reliable - made in Japan. They even have a model
that can be fitted outside.
