Everyone asks how much it costs. Almost nobody asks how long they'll be without hot water.
That second question deserves more attention than it gets, because a tankless conversion is not a swap. The old tank comes out. Gas pipework frequently needs upsizing. New venting has to be routed and terminated. Condensate needs a drain. Water connections move. Depending on what's involved, that's a day — or it's a day, a wait for a part, and another day.
And somewhere in the middle of that, a household still needs to wash.
A straight tank-for-tank replacement is usually a morning, and most people plan around it easily. A conversion is a different proposition, and it's worth knowing which one you're buying before the van arrives rather than at four in the afternoon when the venting turns out to need a route nobody anticipated.
So we set out the changeover plan alongside the price: how long, in how many visits, and what you'll have in between.

Six things agreed before a date is booked.
Where gas work, venting, and electrical are all straightforward, frequently one. Where a gas line needs upsizing along a difficult route, or venting needs a new penetration through a wall, it's sensibly two — and that's better planned than discovered.
Not "we'll be as quick as we can." An actual estimate, so you can plan showers.
On a two-visit job, frequently yes — preparatory work first, changeover on the second visit, with hot water continuing throughout the gap. This is the single most useful thing to ask about, and it's rarely offered unprompted.
Gas, venting, condensate, and water connections have a sensible sequence, and it affects how long the supply is interrupted.
For venting through a finished wall, or electrical work on an electric unit.
Corroded pipework behind it, a flue route that isn't viable. You hear it then, with options, rather than finding out from the invoice.
The six items behind the unit price — and the ones that decide whether it's one visit or two.
A tankless unit's input while running far exceeds a storage heater's. The existing line frequently isn't large enough, and meter capacity needs checking too. Running a larger line through a finished property is real work.
And it matters beyond scheduling: an undersized gas line means the unit can never reach full output — behaving exactly like a heater that's too small.
Tankless units need their own, correctly routed and terminated with proper clearances. Condensing models need appropriate material for acidic condensate. Storage heater venting is rarely reusable, and a new penetration through a finished wall is a considered job.
Condensing units produce condensate needing a drain and frequently neutralisation.
Minor on gas units. On whole-house electric, potentially substantial — sometimes a service upgrade, which is a separate trade and a separate timeline.
Scale is the primary enemy of a tankless heat exchanger.
Allowing the unit to be flushed and descaled without draining the system. Cheap now, expensive to retrofit.
A failed tank is the worst moment to convert. You have no hot water, the pressure is on, and gas or venting complications surface at the least convenient point.
Where the tank has already failed and a conversion isn't straightforward, a like-for-like replacement now and a planned conversion later is frequently the better call — and we'll say so rather than pushing a conversion through under time pressure.
Because it isn't right for everyone.

Think again"Endless hot water" is true and slightly misleading. It won't run out — but only at the rate it can deliver.
How much at once, cumulative across every fixture running simultaneously.
How far the water must be lifted — your output temperature minus what's arriving.
Any unit delivers high flow at a small rise, or modest flow at a large one. It cannot do both, and every headline rating is quoted at a rise that flatters it.
Colder incoming water means a bigger lift — a unit comfortably serving two showers in July may manage one and a half in January.
The specification has to survive your coldest day.
A characteristic worth understanding before you own one.
The burner fires and the exchanger heats. Brief, but real.
Which applies to any heater — the cold water sitting between unit and tap must clear first. On a long run this is the larger part of the wait.
A slug of unheated water arriving when a tap is turned off and quickly on again. Modern units with buffer tanks have largely reduced it.
Some units need a certain flow to fire at all — a trickle may not trigger it.
Recirculation is the answer where the wait matters, and it should be specified deliberately at installation rather than added later. A cheaper alternative sometimes applies: a point-of-use unit at one remote fixture.
The long service life is what makes tankless worth the installation. It's conditional, not automatic.
Water passes through a narrow heat exchanger at high temperature. Minerals precipitate onto those surfaces, and even a thin layer insulates the exchanger, reduces output, and forces the unit to work harder.
Annually as a baseline, more in hard water or heavy commercial use.
A descaling solution circulated via the service valves — which is exactly why those valves belong in the original installation.
Output drops gradually enough that people adjust. Then error codes. Then the exchanger fails — the most expensive component in the unit.
An actual estimate, per visit, so you can plan rather than hope.
On a two-visit job, preparatory work first means hot water continues through the gap. Rarely offered, frequently possible.
It's the item most likely to turn one day into two, and it's better known in advance.
Gas, venting, condensate, electrical, treatment, and service valves — itemised.
Descaling is what delivers the service life you're paying for.
Especially where yours has just failed and a conversion would be rushed. Planning it properly later beats forcing it now.

Where gas pipework needs upsizing along a difficult route, or venting needs a new penetration, it's sensibly two — and you'll get an estimate per visit rather than a shrug.
Frequently, yes, on a two-visit job. Gas, venting, and condensate work can often be done with the existing heater still live, so the changeover itself is short. It's the most useful question to ask and it's rarely offered unprompted.
Because a tankless heater isn't one. Gas lines frequently need upsizing, venting differs entirely from a storage heater's, condensing units need condensate drainage, and hard water needs treatment. That's the gap in most cheap quotes.
Possibly not. A failed tank is the worst moment to convert — no hot water, time pressure, and complications surfacing at the least convenient point. Where a conversion isn't straightforward, a like-for-like replacement now and a planned conversion later is frequently the better call, and we'll say so.
Often, yes, and it's the item most likely to add a second visit. Tankless units draw a high gas input while running, and a line sized for a storage heater frequently can't supply it. An undersized line means the unit can never reach full output.
It means it won't run out — but only at the rate it delivers. Exceed that with too many fixtures at once and the temperature drops rather than the supply stopping.
Colder incoming water means a bigger lift, and flow trades against temperature rise. The same unit serving two showers in summer may manage one and a half in mid-winter. Sizing must use your coldest case.
For a single fixture, comfortably. For a whole house, it requires substantial electrical service — sometimes a service upgrade, which is a separate trade and a separate timeline on top of the plumbing.
Isolation valves letting the unit be flushed and descaled without draining the system. Cheap at installation and expensive to retrofit — and descaling is what determines how long the unit lasts.
Annually as a baseline, more often in hard water or heavy commercial use. Scale reduces output, triggers error codes, and eventually destroys the heat exchanger.
The unit takes a moment to fire, and the cold water already in the pipe between heater and tap has to clear — which applies to any heater. On long runs, recirculation or a point-of-use unit addresses it.
You'll hear it then, with options, rather than finding out from the invoice. Corroded pipework behind an old unit and unviable flue routes are the two most common surprises, and both are better discussed than assumed.
The price gets asked about. The interruption rarely does — and a conversion is not a swap. Old tank out, gas possibly upsized, new venting routed and terminated, condensate drained, connections moved. One day or two, and a household still needs to wash somewhere in the middle of it.
Total Plumbing Solutions sets out the changeover plan with the quote, keeps the old tank live through the gap where a two-visit approach allows, checks the gas supply before booking a date, and fits a storage tank instead where a rushed conversion would be the wrong call.
