Rugg, C.J.
The question in this case is whether a covenant to heat premises demised under a written lease can be implied. There was evidence tending to show that the les*346sor leased to the defendant by a written lease two rooms on the second floor of a three-story building on Central Street in Lowell. On the first floor were stores and a stairway leading from the ground floor to the second. The third floor was formerly occupied as a recruiting station. The demised premises, used for conducting a brokerage business, were at the extreme right side of the second floor, a front room being occupied as a board room and a back room as a private office for the manager. There was one radiator in each of the two rooms, connected with pipes. The heating apparatus was in the cellar of the building. The rooms were not adequately heated. There were electric fixtures on the premises, whereby electric heaters might have been installed. The attorney for the defendant said to the lessor that the defendant’s manager was “complaining about the lack of heat in the premises, that it could not be used for a brokerage office, and” asked the lessor “what he could do about it;” the lessor replied, “we are doing the best we can; we can’t do any better.” The lessor testified that he did not run the heater or have anything to do with it, but attention was given to it by the occupant of the first floor, who agreed, in consideration of his lease, to heat the entire building including the rooms demised to the defendant. The tenant of the first floor testified that he operated the heating plant for the building and never received any complaints for lack of heat.
There was not evidence sufficient to warrant a finding of an implied covenant on the part of the landlord to heat the demised premises. The parties entered into an elaborate lease in writing. Its natural implication is that the parties embodied in that formal instrument the terms of their contract. Snider v. Deban, 249 Mass. 59. It contains nothing about heat. It does not appear that there was any conversation on the subject as preliminary to the execution of the lease. There was no evidence of a prevailing custom in Lowell on this point. The mere presence of the radiators in the rooms did not warrant the implication of a covenant to heat. It is not unusual for parties to make a special contract respecting heat when there are radiators in the demised premises. The evidence was to the effect that this heating *347plant was in the management and control of another tenant. If this evidence was discredited, there was nothing to show that the lessor had control or management of it. The lessor may have intended to relieve himself entirely of responsibility as to heating by omitting all reference to the subject from his lease to the defendant, and putting the obligation entirely upon another tenant. That is one rational inference from the facts. The conversation of the lessor in reply to a complaint as to heat was equivocal and not an admission of obligation.
The case at bar is distinguishable from decisions like Jackson v. Paterno, 128 App. Div. (N. Y.) 474; Berlinger v. Macdonald, 149 App. Div. (N. Y.) 5, O’Hanlon v. Grubb, 38 App. D. C. 251, where there appear to have been no other reasonable means of heating the premises except from a central heating plant in the control and management of the lessor connected directly with radiators in the rooms of the lessee used for a home.
Conformably to the terms of the report, judgment is to be entered for the plaintiff in accordance with its declaration.
So ordered.
