| The costing estimate provided by
this tool is based a statistical analysis of 60 contractor quotes and
actual installed costs in multiple unit residential buildings in southwestern Ontario
since 2003. The sample buildings were all heated by gas-fired hot water
boiler systems, and varied in size from 24 to 375 suites and 3 to 29
floors above grade. The relevant variables were collected and analyzed
using multi-variate linear regression, to arrive at a costing figure
that is accurate within 10%, 9 times out of 10. |

Floors Above Grade (3
to 30)
Enter more than 3 only if the boiler room is at ground level or
below grade. Leave the value of 3 for penthouse boiler rooms. |

Notes:
1. Pricing calculations assume a multiple-boiler modular plant, and that piping and pumping will be re-engineered
to make best use of the plant for energy efficient operation.
2. Condensing boilers, which offer the highest possible energy efficiency, are not evaluated in this calculator
but can be considered at most sites. Condensing boilers are very sensitive to site conditions
and operating practices, so they require careful site-specific evaluation.
3. This is not a formal quote, but an indication of pricing that can be expected under
competitive market conditions. Efficiency Engineering Inc. does not install heating plants.
We act as Owner Representatives to ensure that our clients get the best possible value when upgrading their
building assets.
4. These calculations include an allowance for professional design and project management. An experienced professional engineer
should always be retained to ensure system efficiency, regulatory compliance, overall quality, and competitive
market pricing.
5. Original heating plants are often oversized, so direct replacement of existing equipment often costs more than
an engineered solution that matches plant capacity to calculated requirements.
6. There is a widespread shortage of skilled trades and labour to perform this type of installation. However
the mechanical construction industry is seasonal, so pricing is lowest at those times of the year when labour is
most available. It is important to plan ahead and tender early to take advantage of labour availability.
