← Boiler Replacement Bid Calculator
This calculator vs. ServiceTitan
Two different shapes: ServiceTitan is an account-based field service management platform for running a hydronic/steam company's whole operation. This page is a free, private worksheet for one question — what should this one boiler replacement cost, given its scope, its plant, and its extras, before you quote it.
What each tool is for
ServiceTitan is a field service management platform, founded in 2007 by Ara Mahdessian and Vahe Kuzoyan, headquartered in Glendale, California. It serves HVAC, plumbing, electrical, and other trades with scheduling, dispatch, invoicing, marketing, reporting, and job costing across a whole business, with a mobile app for crews in the field. It is an account-based platform: you sign up and use it as an ongoing service across a whole company, not a one-off calculator. ServiceTitan's own pricing page is not reachable from this session to confirm today's exact plan names or dollar figures, so no price for it is invented here: only its well-documented identity and category — field service management software serving HVAC and plumbing among other trades, sold as a subscription account — are stated, and no dollar amount for ServiceTitan appears on this page.
This calculator does none of what ServiceTitan does. It does not schedule techs, dispatch crews, or invoice a customer, and it stores no customer or job record on a server. It takes one job's scope (like-for-like swap, condensing upgrade, or steam-to-hot-water conversion), system, fuel, input MBH, heating zones, and flue height, plus whichever of an indirect water heater, a chimney liner, an oil-to-gas conversion, and primary/secondary piping the job needs, and your crew wage, payroll burden, travel, overhead, and target margin. It turns that into the price, the labor hours behind it, the price per input MBH, the effective hourly rate, and the walk-away price below which the job loses money — plus, if you already have a price on the table, a check of whether it clears that floor. It also runs three comparisons the plant bid alone does not show: the same plant priced under all three scopes, a same-visit patch against a full replacement and the winters of callbacks it usually costs, and the standard bid against a customer-supplied boiler or a Saturday no-heat call. It runs free in any browser, keeps no account, and uploads nothing you type.
| Question | Where to answer it |
|---|---|
| I run a hydronic/steam company and need scheduling, dispatch, invoicing, marketing, and job costing across every crew and every job. | ServiceTitan, or a comparable field service platform — running a whole company is not something this calculator does. |
| What should I charge for this boiler replacement, given its scope, its plant, and its extras? | This calculator — free, instant, private, no account. |
| How much more does a steam-to-hot-water conversion cost than a like-for-like swap on the same MBH? | This calculator's "Same plant, three scopes" comparison, not a flat per-boiler price. |
| Does tonight's "just patch it" call still cover the visit once this winter's callbacks are on the ticket? | This calculator's patch-vs-replace comparison. |
| Does hanging the boiler they bought at the supply house still cover the set, or does a Saturday call still pay after overtime? | This calculator's owner-supply and access-timing comparisons. |
| Is the price I'm about to quote still above my walk-away cost for this job? | This calculator's compare-to-proposed-price check. |
| I need one shared account so my whole crew is scheduling, dispatching, and invoicing the same way. | ServiceTitan, or a comparable field service platform. |
| How does the math behind a boiler replacement bid actually work? | This calculator's own pricing walkthrough. |
| Do I need to create an account or sign up to use the tool? | This calculator: no. ServiceTitan is used through a subscription account. |
Most hydronic and steam shops get different value from each: ServiceTitan (or a comparable field service platform) for scheduling, dispatch, invoicing, and job costing across a whole company as an ongoing subscription, and a private calculator like this one for an instant, no-login answer to what one boiler replacement should cost from its scope, its plant, and its extras before a business system is involved. This page's own figures are a pricing model, not a heat-loss calculation, a fuel-gas-code determination, an invoice, or a signed proposal.
This tool needs no account and no sign-in: it is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off.
Common questions
Should I use this calculator or ServiceTitan?
They do different jobs, and a hydronic or steam contractor of any size will likely end up touching both eventually. ServiceTitan is a field service management platform, founded in 2007 by Ara Mahdessian and Vahe Kuzoyan and headquartered in Glendale, California, used by HVAC, plumbing, electrical, and other trades to run scheduling, dispatch, invoicing, marketing, and reporting across a business, sold as an ongoing subscription account. This calculator does one narrower thing: starting from scope (like-for-like, condensing upgrade, or steam-to-hot-water conversion), system, fuel, input MBH, zones, and flue height, with an indirect tank, a chimney liner, an oil-to-gas conversion, and primary/secondary piping as their own line items, plus crew wage, payroll burden, overhead, and target margin, it turns that into the price, the labor hours behind it, the price per MBH, the effective hourly rate, and the walk-away price below which the job loses money, before any of it touches a business-management system. It also prices a same-visit patch against a full replacement, and a customer-supplied boiler or a Saturday call against the standard bid. It runs free in any browser, keeps no account, and uploads nothing you type. A contractor who already schedules techs, dispatches crews, and invoices across every job is better served by ServiceTitan or a comparable field service platform; a shop that wants an instant, private answer to what one boiler replacement should cost from its scope, its plant, and its extras is in the right place here.
Does this calculator size the boiler, flue, or gas piping for me?
No. Hours and material rates are ballpark shop figures you can edit, not a heat-loss calculation, a fuel-gas-code determination, or a chimney design. Whether a flue needs a liner, what size the liner should be, and whether the combustion venting meets code for the fuel and appliance are still a judgment call for the licensed tech on site. Verify every figure against your own takeoff and a licensed technician before you submit a bid or pull a permit.
