[1] If, on the evidence, the plaintiff could recover either for breach of warranty or negligence, the motion for dismissal was improperly allowed. There was an implied warranty by the original defendant that the stove would heat the plaintiffs’ home without exploding. See G.S. 25-2-315. We believe the principles applying to the facts of this case are found in Insurance Co. v. Chevrolet Co., 253 N.C. 243, 116 S.E. 2d 780 (1960); Lemon v. Lumber Co., 251 N.C. 675, 111 S.E. 2d 868 (1960); Driver v. Snow, 245 N.C. 223, 95 S.E. 2d 519 (1956). If the damage to the plaintiffs’ property was proximately caused by the explosion of the stove and the stove exploded as a result of a defect which was latent so that the plaintiffs did not know and by reasonable diligence would not have known about it, the original defendant is liable to the plaintiffs for breach of warranty. We believe the evidence that the stove had previously malfunctioned with the evidence that *418the fire was started by an explosion and the assistant fire chiefs testimony that it was the heater that was burning “so violently” was evidence from which the jury could conclude that the explosion of the stove was a proximate cause of the destruction of the plaintiffs’ home.
The defendants, relying on Insurance Co. v. Chevrolet Co., supra, contend that the plaintiffs are barred because if there was a defect in the stove it was apparent to the plaintiffs. In Chevrolet Co. our Supreme Court held the plaintiff could not recover either for breach of warranty or for negligence after an automobile had allegedly burned as a result of defects in the wiring and ignition system. In that case the plaintiff alleged the owner of the automobile had continued to drive it after she discovered the ignition system was defective and the engine of the automobile was saturated with gasoline whenever she drove it. The Supreme Court held a demurrer was properly sustained. The Supreme Court said the owner of the automobile was negligent in continuing to drive the automobile when she knew of the defects and this negligence was a bar to recovery for either breach of warranty or for negligence on the part of the defendant automobile dealer in not repairing the automobile. We believe Chevrolet Co. is distinguishable from the instant case. In Chevrolet Co. the plaintiff alleged the owner of the automobile knew the ignition was faulty and the engine was saturated with gasoline while the automobile was being operated but continued to use the vehicle. In the instant case the evidence showed the plaintiffs knew the heater malfunctioned when set on medium or low, but did not know it malfunctioned on pilot. They had previously set the heater on pilot and left it for as much as 24 hours without difficulty. We do not believe the jury could only conclude from this that the plaintiffs knew, or by reasonable diligence should have known, the heater would malfunction when set on pilot. We hold it was error to grant the defendants’ motion for summary judgment on the ground of a breach of implied warranty.
[2] As to the question of negligence on the part of the original defendant, we believe the evidence shows the heater malfunctioned shortly after it was installed and continued to malfunction after being repaired once by the original defendant. The original defendant was subsequently notified on several occasions that the *419heater was malfunctioning but did not send anyone to repair the heater. If the jury should believe this evidence, they could conclude the original defendant failed to do something a reasonable man would have done. This would be negligence. We believe it is a jury question as to whether the plaintiffs were contributorily negligent in leaving their home with the heater on pilot when they knew the heater would malfunction when set on low or medium. The plaintiffs also contend that res ipsa loquitur applies. We hold that the original defendant did not retain control of the heater which makes res ipsa loquitur inapplicable. See O’Quinn v. Southard, 269 N.C. 385, 152 S.E. 2d 538 (1967).
The plaintiffs also assign error to the court’s sustaining objections to questions asked of Mr. Arrington and Mr. Bryson. The record does not show what the answers of these witnesses would have been and we do not pass on these assignments of error. See Eubanks v. Eubanks, 273 N.C. 189, 159 S.E. 2d 562 (1968).
For the reasons set out in this opinion, we reverse the judgment of the superior court and remand for trial.
Reversed and remanded.
Judges MARTIN (Robert M.) and WELLS concur.
